hello everyone!

 

I hope somebody can help me out with this problem that i have.

 

Everyone know, at least thats what i think, that the sprint version of the iphone 5 does not use a sim card because its a cdma phone, right?

so why am i getting this message that says "NO SIM CARD INSTALLED" and instead of having the sprint name on the top corner, all there is is the same message, NO SIM.

 

A little weird..

I tried cleaning the tray and many other things like resetting my phone to factory settings, resetting network settings...and nothing.

I also send an email to sprint about my problem, and im waiting for their response, but I'm paying them a visit tomorrow to see whats up.

 

Has anyone had the same issue? and if yes, what did you do to fix it?

 

THANKS!

I believe the iPhone 5 still requires a nanoSIM for the LTE portion (at a minimum) of service. If you got it second hand, you might need to get a NanoSIM from Sprint

I think Sprint is just trying to force Newco to sell Sprint some of their PCS spectrum in return for Sprint leaving the deal alone. I also think that would be the most beneficial out for Sprint (and consumers) - Sprint doesn't need that AWS spectrum, nor do they need another network to try and integrate into their own... T-Mobile REALLY needs the AWS Metro PCS' spectrum and some of their PCS spectrum, but not all of the PCS spectrum (If you look AJ's spreadsheet on how much PCS spectrum Newco would have should the deal go through, it's bordering on obscene in some markets).I think this would also be the best outcome for consumers: it would create a much stronger Sprint and a much stronger T-Mobile, and more competition is much better.

The round table format ate hairy spiders when drunk. Its towers became bloated after swallowing a mouthful of baby formula. The baby ate his poisoned barbeque chicken ribs without A1 steak sauce. Fix the chair leg before somebody trips and breaks their sister's glass. It peed shards of LTE droppings from bubbly fermented apples. Doctors gouge the helpless when options appear dangerously silly for perpendicular slicing. Around 2pm there was another explosive diarrhea attack that drove Dan to SMS SoftBank, which viciously countered MetroPCS;s audacity to compete. Meanwhile, Mexicans discovered sparkly water of Rio which tasted like rainbows.

LightSquared, however, beamed sparkly clusters of spectrum at GPS, causing multitudes of bananas being paranoid about world domination. This exacerbated an enormous flock of pelicans into your mother's house. Then seagulls confronted Darla with weapons manufactured in Korea

Sprint isn't going to allow garbage wifi connections ruin the sparkling reputation their voice service has earned. I've made calls over my wifi, which is really fast and low latency, and they were garbage. If people want to call on wifi, there are apps to allow it, no reason for sprint to put their name on substandard voip.

 

Here is a speed test of my wifi for reference:

 

I think if they had a GAN/UMA based system like T-Mobile and some other providers, it would be great and alleviate a lot of those concerns. GAN/UMA essentially makes your phone it's own femtocell (like its own Airave) over wifi, Sprint's network would just see you as connected to another base station

No carrier on the planet has perfect indoor coverage.

 

Sprint should license the technology from its MVNO Republic Wireless and have it built into all of its future Android handsets.

 

Its absolutely awesome, it completely eliminates the need for an AirRave and more importantly, its like taking your own AirRave with you to OTHER places that have poor indoor coverage. Brownstone apartment buildings, homes near unfortunate geographic features, sports stadiums, industrial or office settings, lower levels of a shopping mall. etc.

 

There are tons of places that have poor indoor signal penetration and an available wifi network, it really is that good of a feature, you quickly start to view it as indispensable once you get used to having it on your phone.

The idea of a decent reliable official wifi calling tech that allows you to use your number and is totally integrated, as T-Mobile has had and other companies like Republic Wireless offer would be an awesome advantage. Full bars wherever you can get WiFi would be awesome!!!

So I'm noticing a delay of about 10 seconds or so before the LTE connection gets moving. What I mean is I'll type msn.com into my phone browser and I'll wait a good 10 seconds before the page starts to download, which at that point it is quick to load the images and elements. I've noticed the same thing with Speed tests...I'll tap begin start and wait 5 seconds before it begins.

 

Is this normal? I'm guessing it might be related to DNS/waiting to resolve ip addresses or something but haven't done much research beyond this observation.

 

For reference, I'm in a market which is testing but has not yet launched.

I've never experienced anything but the opposite unless I was on the edge of a 4G cell, in which case data was unreliable in general. In fact, if I have even just a decent 4G connection the loading is just about instantaneous both in terms how quickly it begins and how long it takes to finish. What device do you have? Is this behavior the same even when you know you have a good 4G signal?

Been unable to connect to eHRPD as of today. Sometimes I get on for a few seconds before it switches back to EvDoA. I'm in North San Jose.

Same here, at home in South SJ/Willow Glen and in Saratoga as well.

Ahh so its the opposite of what I thought. What about my other question about capacity? If everyone is defaulting to LTE 1900 and it starts to get congested, would any new connections connect automatically to LTE 800 instead?

That's how it should work. In fact, the ideal will be, depending on what Sprint does with Clearwire, if you're in a Clearwire area with LTE, you will be on the LTE 2600, then if you go out of range or there is congestion (unlikely) you will switch to LTE 1900, then as a last option you'll go to LTE 800. Since the LTE 800 signal has better penetration and farther reach, they want to keep congestion on that as low as possible, as it will be serving more people than either the 1900 or 2600 would.

Interesting, I wonder if this vulnerability is resolvable, and, the question begs to me asked.... did WiMax have the same problem?

I am wanting to know for people who had bad coverage with 3G whether their coverage got better or worse with the 4G LTE. I have a few phones in areas where the 3g coverage right now is almost non existent inside and I am thinking about asking for an airwave to help with signal if 4G wont be any better when it finally comes.

Your 3G coverage might improve, but the 4G is likely to be equivalent to your 3G right now - that is until later on with LTE 800 sometime in mid 2013, but you'd need a new phone for it anyway. If you are having trouble right now, I'd go ahead and ask for the Airave - you can always send it back when your signal gets better.

Here is one in Santa Fe with the outer cover removed.

So basically they seem very similar to regular towers, but with the antennas for each sector much much closer together, right?

Are you referring to those towers that look like they're just a pole with kind of a cylinder at the top sorta? I've been curious about those too.

Sprint just received 3 billion dollars from Softbank... I would have hoped for more than just 9 cities?

Come on Sprint.... Kick it up a notch!

You're assuming that it's purely an issue of money that's keeping them from deploying more quickly, when in reality I think they're moving as quickly as they possibly can already. Remember, Network Vision will both save Sprint a lot of money and will help to retain customers... though it's for different reasons, they want it done just as badly as we do.

Sprint (along with some other carriers) has panels on a building on campus at my college, and I took a picture of what looked like NV panels to me. What do you guys think?

What's involved when they have to go back to the towers to install equipment for LTE 800? Is it just an additional carrier card or are they actually going to have to go up the towers and do a lot of additional work? How labor and time intensive is it compared to the original network vision upgrade of sites? I'm just curious as to, when they actually start rolling it out, how long that overlay will take. Also, what are the FIT markets for LTE 800? Is it Waco again? Do they have it up?

I must be getting old. I read the article and I don't get it. What does it do? It sounds like it is redundant and not innovative at all. Am I missing something?

It's an international GSMA accredited standard that is looking to make the following things interoperable like SMS and MMS:

• Standalone Messaging
  
• 1-2-1 Chat
  
• Group Chat
  
• File Transfer
  
• Content Sharing
  
• Social Presence Information
  
• IP Voice call
  
• Best Effort Video call
  
• Geolocation Exchange
  
• Network based blacklist
  
• Capability Exchange based on Presence or SIP OPTIONS
  

I thought this was interesting, does anyone know if Sprint has any intention of implementing the RCS standard on their LTE network as well?

I've been unable to connect to the new one by 880/Montague that I found twice last week (and was added to the Sponsor-only "NV Sites Complete" thread.) Tried last night and today.

 

First time that I've been unable to connect to previously-found LTE. I only tried for a few minutes though.

I was unable to connect to LTE at all on Saratoga in the places I had it previously, but I noticed right near Saratoga and 85 there was a tower that looked like it had NV work being done on it, so maybe they had deactivated it there as they were working on it in the area... I don't know.

I haven't seen much expansion is this market for the last two weeks. It used to be that you could find new towers weekly, but hard to say if work is done to prep more towers or if people and equipment have been sent to help out LA and other markets.

There is expansion, but more slowly, and they seem to be hitting the north (and by north I mean practically Sacramento) bay much more heavily than any other area. I can also say that I in the South Bay am not seeing LTE in a lot of areas I did previously... they might have started the blocking.

LMAO, that would be one butt-ugly logo.

I have to say, I think all of the comments from Sprint saying 'Oh no we don't plan on acquiring Clearwire at least not anytime soon' etc etc is mainly to keep the stock price low, especially after that 70% increase in share price after the announcement was made and rumors started flying. I think Sprint is being smart about this, playing it close to the cuff until it's essentially a done deal, the same way Softbank and Sprint handled their negotiations and partnership.

Data only devices tend to have much better reception due to design and the fact that they can usually consume higher power.

I wonder how much of a limitation Sprint's financial situation has been on the NV pace, vs other constraints. Using the money to speed up NV would seem like a wise use of their new resources. If Softbank is looking to take on the AT&T/VZW behemoth, they can't even begin to think about that until NV is substantially complete. But even if they decided they did want to throw money at it to speed it up, were Sprint's resource constraints really the holdup? Or do the other factors, such as equipment availability, qualified contractor availability, planning lead times, permits, other local regulatory headaches, and even the damn birds the bigger constraining factors?

I don't think that Sprint's financial situation has been the main constraint on NV - I think there is just a finite number of RF engineers, contractors, negotiators, etc - all of those things that you mentioned. If Sprint could speed up deployment of NV I think they would do it... they save on roaming, they have happier customers, they save on power consumption with the consolidation of the IDEN and CDMA networks and the new equipment. Sprint has EVERY reason to want NV to go as quickly as possible, because the more quickly it's deployed the more quickly they can really start earning money back on it.

Does anyone know why the cell phone market is a closed system in Japan? Is it forced by the government or a commercial reason.

 

When you go to Japan, you can't buy a SIM card like you can is most other countries, you have to rent one or rent a phone. Costs hundreds of dollars per week I hear. Norway is the same way, a little more open though.

In the past in was because of Japan's use of the Japan-only PDC cell phone system, which was an analog of GSM in Europe and TDMA in the US. There was no actual GSM network for a SIM card to be used with. There are R-UIMs (like CDMA SIMs) that can be used with KDDI's CDMA in Japan, BUT, as a way of making it more costly for non-Japanese countries to market cell phones in Japan and therefore give a boost to Japanese manufacturers, they reversed the TX/RX (send and receive) bands for CDMA in Japan so that CDMA phones in Japan were incompatible with those anywhere else in the world. HOWEVER, with the arrival of WCDMA/UMTS 3G in Japan in the last five years or so, you can finally buy a prepaid SIM that will work with unlocked phones on some Japanese networks, the only caveat is this:

"Due to past criminal abuse of prepaid phones, phone sellers are required to verify the identity and place of residence of their customers. Typical proof can be in the form of a Japanese driver's license, a Japanese passport or an alien registration card. Some stores will accept foreign passports along with a hotel address as verification." (Via http://www.japan-guide.com/e/e2223.html)

The Japanese phone market became more open with baby steps and almost in spite of itself - a bit like what is happened in the US.

Actually, I think one of the main reasons Sprint hasn't moved the using SIM cards yet is because, unless you do what Verizon has done (kind of jury-rigging their authentication system to allow one SIM card for LTE and CDMA), the SIM card would only switch over the LTE part of the service and not the CDMA (meaning you might end up with working LTE data but not CDMA voice and data). That particular jury-rigging that Verizon has caused them a lot of grief on their network and a few outages I believe as well. I believe that the only reason Verizon implemented SIM cards in their LTE devices with their jury-rigging technique is because it was a requirement placed on the spectrum that they purchased (they couldn't prevent carrier interoperability, same reason their Galaxy S3 is a world phone, for example). As LTE networks worldwide and in the US start to become compatible with one another, it's more likely that we'll see Sprint start to use SIM cards...

All that said, how does the SIM card work in the iPhone? Can you simply switch a Sprint nano-SIM into a Verizon iPhone 5 and have it work? If so it would indicate that Sprint is just being a handset bully.
