I decided to change my data connection to LTE only for my trip from Texas to Kansas. That way I should not have to toggle to get LTE to connect since there would not be a CDMA connection alrady established connection to change when LTE was available.

 

Well guess what? LTE still would not connect even though the iPhone had and LTE connection.

 

1. I connected once in Wichita Falls but soon lost it and never connected again there even though the iPhone maintained an LTE connection while in Wichita Falls.

 

2. iPhone connected at the south Kansas border, Evo finally connected after toggling.

 

3. Evo never connected in Wichita KS, iPhone always connected

 

4. Automatically connected from Andover, KS to El Dorado, KS

 

5. Finally automatically connected in Overland Park.

 

I cleared the LTE file so I could log all connections on the trip. No connections were logged until I set the connection to LTE/CDMA/EVDO auto when I got home.

 

Note: When connected LTE, there were not NID or BID info in netmontior when LTE only selected.

I discovered a different way to get "LTE only"

First, you dial *#*#4636#*#*

Then you scroll down a tiny bit and there is a little triangle on the right. If you press that, you get a list of options. If you select the bottom option "LTE, CDMA" you will connect to 4G without any problems. If no 4G is available, then you will revert to a 1X connection. This trick worked great for me when I was mapping 4G in my area. There are some downsides. For example, you can't get 3G. Also, I didn't have any luck staying connected to 4G for long. YMMV

To change back you do the same thing and select "CDMA + LTE/EvDo auto"

      iPhone XS and XS Max are Apple's newest flagship phones, and the successors to Apple's 2017 iPhone X. They have the new A12 Bionic chip, improved cameras and faster FaceID, and come in a beautiful Gold Stainless Steel finish in addition to the Silver & Space Gray options. They are available in the same 5.8" Super Retina display as with the X, and the bigger 6.5" Super Retina. They are available in 64GB, 256GB, and 512GB configurations.
      Apple added Dual SIM technology to the 2018 iPhone's, with one physical SIM, and one eSIM. (eSIM feature not currently supported by Sprint, but is said to be coming later). These phones also feature IP68 water-resistance (iPhone X was IP67) which gives you protection in water for up to 30 minutes in up to 2m of water.

      I recently went on an 8 day cruise from NYC to the Caribbean that stopped in Turks and Caicos, Puerto Rico, and the Dominican Republic. My first stop was Grand Turk and there I opted for the free roaming. My S9+ automatically connected to Flow's (Cable & Wireless) LTE network where I received speeds of around 120kbps on average with boosts of up to 150kbps. Something worth noting is that on speed tests, the server prefers to default to Sprint's Miami server as opposed to local servers. Speeds were more than adequate for any amount of web browsing and honestly felt much faster than in reality. It helps that using Chrome will save you data by not loading pictures on certain sites unless you click them.
      In Puerto Rico, I connected to Band 13 on the way into the port in San Juan but once I was in the city, my phone never left Band 41. While the phone was usable, speeds remained significantly lower than what I've come to expect from 3xCA in the mainland U.S. Data speeds peaked at around 25-30Mbos but on average were in the 5-10 Mbps range even on LTE+. Signal remained strong everywhere though. 
      Finally in the Dominican Republic, I entered in Amber Cover which is in Puerto Plata. My phone latched onto a weak Band 2 LTE signal in the port from Altice (called Orange Dominicana in SignalCheck). I had trouble loading pages though. Once off of the ship and out in the open, I had a much stronger signal which allowed me to browse the internet without a hitch. Because it was the last day of my trip, while at the beach I decided to purchase the 24 hour high speed pass for $5. My speeds went from 120kbps to 65Mbps in less than 5 seconds. In some areas speeds were slower, particularly at the port where it struggled to break 2Mbps. Now, back on the boat my phone is flipping between weak Band 4 LTE and overloaded Band 5 HSPA+ from Claro (called Verizon Dominicana in SignalCheck Pro). Here is the difference in speed from before and after purchasing the high speed pass.

      Sprint 4G Rollout Updates

      The iPhone is something many people see as a status symbol. Many who have never owned one, long for their upgrade date so they can go out and buy the "exclusive" iPhone that they have been denied access to for years. Even some who had the iPhone, and then switched carriers, long to repurchase another. Yes, the iPhone is a well made smartphone with access to a loaded app store, and has many desirable features. But is it really better than Windows Phone, Blackberry or Android models?
      When Apple entered into a contract with AT&T, they remanufactured the RAZR craze and how the artificial scarcity of the device created such huge demand. The RAZR was a good device, and you may argue it was well ahead of other phones at the time of its release, but the other manufacturers caught up quickly. Apple used a similar strategy and it has paid off immensely. The iPhone is now available on the top 3 carriers in the U.S., but is still seen as a status symbol in many circles. As if only a few people have access to it. One could make a strong argument that the Samsung Galaxy SII is a superior smartphone, but still many customers line up to get the iPhone instead, because their inner hoarder says they NEED it, and the products perceived coolness and limited availability only add to the whole experience.
      The concept of artificial scarcity is simple. You take a product that is plentifully available to manufacture in mass, but limit distribution to a limited time, limited area, or in the case of the iPhone, limited retail outlets.
      The strategy has worked perfect for Disney. Why let your movies make the gradual descent to the $3.99 Wal-Mart bargain bin? Just keep "taking them out of the vault" and offering them at full price for a few months every couple years and people pull their credit cards out to pay $17.99 for an 85 year old movie and thank Disney for "allowing" them the opportunity to purchase Snow White. Oh, and you get to be a part of a limited privileged club.
      Another notable example is McDonald's McRib. If it was on the menu full time, many people either wouldn't bother going to McDonalds or would order something else, but artificial scarcity commands us to rush in to McDonalds and get several McRibs at a time because we won't have another chance at it for another year. What do we end up with, besides a belly ache and a reason why we don't normally eat at McDonalds?
      We should be immune to this form of advertising by now, as we are constantly inundated with limited time availability and special edition products all around us. However it is still alive and well here on Planet Earth, because it still works. Big time.
      Can Apple keep the air of exclusivity over its iPhone as it continues to broaden its distribution? Or will smartphone buyers move on to other devices? Only time will tell. But many doubt that Apple will play its hand as well in an era post Steve Jobs.

      Sprint 4G Rollout Updates
      Tuesday, January 31, 2012 - 7:46 PM MST
       
      Since last fall, there had been talk of a Samsung Galaxy Nexus launching on American carriers other than Big Red. Sprint has finally announced several weeks ago that it is the another vendor slated for release in the U.S. Suffice to say, many of us out there, especially those adverse to heading to Verizon and paying its premium prices, are excited about the impending release.
      The good news is that Google could be working on an updated version of the Galaxy Nexus. It has unofficially been dubbed the Galaxy Nexus Plus. There is much anticipation that it will be released before Sprint turns on LTE this summer. It’s not the first time an OEM has refreshed a device and re-released it to the market place, which works to our advantage. It’s rumored that the new Galaxy Nexus will have either a 1.5 or 1.8 GHz Texas Instrument OMAP4670 dual core processor. This would be a significant upgrade from the 1.2 GHz dual core processor found in the current Verizon version.
      We don’t know anything about official specs, but it’s also rumored to have an 8 MP camera. This is a noteworthy upgrade to the 5 MP shooter on the Verizon model (which has been lauded by many techies). We already know that the Sprint model will come installed with Google Wallet, per previous announcements. Some rumors also point to a beefier battery as well. The phone should have all the other features that’s on the current Galaxy Nexus, so now all we have to do is wait.

      Sprint 4G Rollout Updates
      Monday, June 25, 2012 - 4:27 PM MDT
       
      As technologies advance, the equipment to use the technology must advance as well. With the upcoming release of 4G LTE in our area (Houston), new equipment will be required to be able to use it. Although Sprint will have numerous data devices to handle the usage by the end of the year, only the Sprint Tri-Band Modem will be available at the rollout of the 4G LTE service.
      Due to the enormous dependence my business has on accessing data in a mobile environment, plus the great increases in data speed available with 4G LTE, this makes getting access to 4G LTE imperative to me. I depended heavily on the Sierra Wireless data devices when I started this business 7 years ago for my source of a reliable method of mobile data transmission. This relationship continued on until the release of the original Hotspot with the 4G service in my area.
      At one point, I was so displeased with past models, that I had sworn I would never buy another Sierra Wireless device as long as I live. This conclusion was reached after having numerous issues with previous hotspot models. There were so many problems that it seemed as if the device was never even tested on the networks it was to be used on. Also Sprint actively blocked reviews of the device, likely to not hinder sales in spite of the problems.
      My need for a new device with both WiMax and LTE capability outweighed my outright dislike of Sierra Wireless products. I proceeded against better judgment, and the Tri-Band modem was ordered even though the possibility of getting a substandard unit once again was always at the forefront of my mind.
       
      On with the show
       

      The official part number of the Tri-Band Modem is 803S. Along with the modem, I also ordered the SSX7077-V desktop cradle. I had to dig through a lot sites to find the information necessary to make this decision for my business. Much to my surprise, even though I was told the cradle was not available yet, I got a Sprint telesales person who was able to use the part number and find they had it in stock.
      Upon arrival I unpacked the unit and cradle...while holding my breath. The device that came out of the box was a pleasant departure from the previous Hotspots I had owned. Above is a picture of the device as it was shipped with all components. There was a small user guide as well but to get the real instructions the user guide must be downloaded from Sprint.
       
      Gone was the one piece blow molded plastic case which allowed no air circulation and caused the prior Hotspots to overheat quickly. Although the display is still too small for my aging eyes (it is actually the same display size as prior units) the change to the case makes it much easier to see in the interior of my van where the device will mostly be used.
      In this picture of the front you can see that there is a new button arrangement as compared to the older Hotspots. Also in the picture is the USB cable for use with the charger or to connect a computer, the AC to USB adapter, the battery and the battery cover. I opened the cradle, which was surprisingly inexpensive, and was delighted to find an additional AC to USB adapter which meant the cradle could be left in place without having to move the adapter around.
      As you look at the modem from the side you can see the antenna ports (the covers are open), the USB connector in the middle and the slot for the memory card. The round hole just right of the left antenna port is the reset button for the unit.

      Here is the same view with the battery and cover installed. Notice that the SD card slot is covered by the
      battery cover.
       

      The opposite side has two switches. The one on the left is a WPS setup button while the one on the right is a slider to mute the unit.
       

       
      The unit sits nicely in the cradle and looks to me to be a solution to help keep the USB port for the charger/interface cable from failing. This has been a major issue with the prior Hotspots. The case of the unit also helps support the USB port to take some of the load off of the circuit board.
      It took quite a bit of digging on the Sierra Wireless site to find out that the antenna ports are for the 4G WiMax band only. The cradle contains 2 5dbi omnidirectional antennas to allow full use of the WiMax network architecture.
       
      Initial testing

      The initial testing of the unit looks promising. The antennas in the cradle for 4G WiMax actually seem to get 3 – 5dBm gain in all conditions tested. The new unit has the ability to search the other bands for signals while staying connected. This allows less downtime between band changes. I notice a lot less disruption when switching bands.
      This unit has better reception on 3G and 4G WiMax than the previous hotspots and even the U600 USB modem I use as well. 4G WiMax is able to connect quickly even at 10% and the cradle has improved stability of WiMax and decreased ping times. For a short time I had access to Sprint 4G LTE as they were testing the towers in my area. The speeds were incredilbly faster. A 10% 4G LTE signal averaged 8.12Mbps download and 1.85Mbps upload. An 80% signal was able to get 35.8Mbps down on my best test and 22.1Mbps up.
      The upload speeds was very unexpected, and much higher than Sprint LTE smartphone devices have reported. This is likely due to much stronger transmit capabilities of the hotspot. I also discovered that when the modem is tethered the cable limits the bandwidth to approximately 20Mbps total speed. It will be interesting to see how it works in the 12 to 14 hour days of hot Houston Weather.
       
      First week in the field
      The Tri Band Modem got pressed into service a little quicker than planned, as my main unit went down with a bad transmission and the U600 USB modem with a Cradlepoint that was in this unit appears to have been damaged by the wrecker’s radio which runs on the edge of the WiMax frequency at 5 watts. The units have been sent in to determine cause of failure and for repairs but I think next time I will make sure all electronics are powered off before getting that close to a transmitter (OUCH!!).
      I am running the same routes in a rental van with the Tri-Band Modem that I normally use the other units on. There is less downtime in the signal gaps I am familiar with and areas where I have had signal problems in both 3G and 4G WiMax are much improved. I have yet to encounter any more 4G LTE signals but am looking forward to the service coming online soon. The unit seems to be running hotter than I would like with a fully charged battery but is actually cooler that the previous Hotspots. The temperature is supposed to soar over the next few days without the cloudiness we have had this past week. So it will be interesting to see if the overheating problems of previous models still occur.
       
      Week 2 – The True test
      The unit is getting worked really hard this week with temperatures outside up near 100 degrees. The GPS is useless with this kind of sun load as the unit will overheat if left in direct sunlight (as the instructions state) in about 20 minutes. The good news is that this is about twice as long as my original Hotspot will last. How anyone can make a unit that requires a clear view of the sky for GPS but can’t handle sunlight is beyond comprehension. A quick check of the Tri-Band’s temperature specs shows that the unit is only rated for 95 degrees. The prior Hotspot was rated well above the century mark but couldn’t even handle 90 degrees for any length of time. The crappiest laptop on the market will handle 105 degrees plus all day long. The true test will be my afternoon calls when the temperatures are high. Battery life has been about 8 to 9 hours which is far better than the prior Hotspots.
      The unit started overheating one afternoon. I can’t say I’m a bit surprised at that, but what is surprising is that it will run steadily as long as the air temp is below 98 degrees. This is a first for Hotspots as they always overheated well before the rated temperature spec. The bad news is the crappy overheat shutdown doesn’t turn off the unit before damage starts to occur, nor does it turn the unit off completely.
      Removing the battery cover seems to help air circulation and overheating some. The button lights are flickering after one overheating but the unit seems to be working fine other than this. It will be interesting to see what happens when it really gets hot here.
      According to the specs 4G LTE takes the least amount of wattage to run so it may not overheat as fast when using 4G LTE. I had the chance to try the modem in the old school 3G EVDO mode as one of my locations is 40 feet underground and that is all that is available at this location. I shut the unit down after 30 minutes as the unit was so hot you could barely handle it even though the temperature underground is around 70 degrees. I would not recommend trying to use this for any length of time if you want the Tri-Band to not overheat!!
       
      My Opinion
      Although Sierra Wireless has made some major improvement in the 3rd generation Hotspot, this is still a unit for the casual user. It is not designed to handle heavy use or outdoor summer temperatures for any length of time. It will be going in my climate controlled cabinet to protect it from the heat next week. I will let you know how it works when the temperature stays below 85 degrees. The improvements in connectivity, reception and stability are worth the investment. As long as you know and adjust your usage for the limitations of the unit.
