A public update to SignalCheck Pro 4.51 is ready! It should be available on Google Play within the next hour or so. There are a few significant changes behind the scenes that are tricky to describe, but the end result will (hopefully) be less (no?) scenarios when the app becomes "stuck" and struggles to display band information until you connect to a new site. Also, Sprint users will see site notes that have been stored with any Sprint-owned PLMN ID, including some of the odd ones popping up lately (312530 most notably). A new icon will indicate when Wi-Fi Calling is active; it appears to be reliable, but there are occasional moments where the OS does not seem to realize it has switched on/off. I will continue working on it. Other pesky bugs were also squashed. The full change log for this release is below: Added additional indicators for AT&T LTE band 14 FirstNet cells. Added icon to indicate when Wi-Fi calling is active. (Pro) Added indicator for Sprint LTE band 41 small cell second carriers. Added indicators for AT&T LTE band 2 small cells. Disabled support for Android 2.3 – Android 3.2. Changed LTE band 14 to display as LTE 750. Changed primary PLMN ID source on Android 7.0+ devices. Implemented Android Oreo notification channels. (Pro) Improved Sprint LTE site notes to appear across multiple PLMN IDs. (Pro) Minor adjustments to animated action bar tower icon. (Pro) Resolved force closes when Background Service is disabled. Resolved issue with app auto-launching regardless of Launch on Device Boot preference setting. (Pro) Resolved issue with cached diagnostic reports not sending. Resolved issue with missing LTE band data when PLMN ID changes. Resolved issue with Show Mobile IP Address failing. (Pro) Resolved issue with some Sprint LTE band 41 cells showing improper MM and SC indicators. Updated PLMN 310580 to Inland Cellular. There are plenty of other improvements still in progress; they will be released as I have time to get them finished, tested, and reliable. I appreciate everyone's support! Thanks, -Mike

I am at DTW now.. I did a lot of walking and testing in the McNamara (Delta) Terminal and it definitely seems improved. I couldn't get B41 without locking out B25/B26, but performance was good when I did that. With no band locking it hangs onto B25. Appear to be three sectors, one at each end of the terminal and one in the middle. 1X signal is excellent and seems to also have the same sector pattern. Upload speeds on B41 aren't great but just about everything else is good. Not sure why a couple speed tests were so slow, trying again immediately after got good results. I was stationary for some and riding the tram on others. See screenshots below. I didn't have enough time to check the North terminal, sorry. -Mike

Found a 15x15 carrier in chambersburg today.

Some devices are reporting 311490 on T-Mobile no matter what I try, but most are not. I will continue looking to figure out a way to make those scenarios work better with "real" T-Mobile site notes logged under 310260. A minor beta update is pushing out now, should be available shortly. It adds AT&T B2 small cells and fixes an issue with cached diagnostic reports not sending. More significantly, a public release is also going out that catches up all the changes the crew has been testing for the past 6-8 weeks. Thank you all for your help, I appreciate it! -Mike

Also keep in mind, it is self optimizing. So you need to let it be for at least a week untouched for it to settle in with its surrounding sites. If your constantly rebooting it it will never complete its optimization.

While it (MB3) can pick up the full 3xCA 4x4MIMO and 256QAM from the macro site, Its limited to a single B41 carrier for the UE side. So around 110mbs. It's more about broadcasting a new clean B41 signal much deeper indoors than the signal from the tower can provide, at the same time improving battery life since its no longer hunting for different sectors and/or macro sites. But if your already seeing great speeds from the macro site everywhere indoors, your just adding latency and lowering your speeds. If you have other locations where you don't have great signal, you might want to consider moving it there.

Speaking of the A, I was at Hartsfield this morning and can attest to the fact that - at least where I was in Concourse D - data speeds have increased tremendously since my last visit to that concourse. I was pulling over 40 megabits per second just before boarding (D38 to be extremely specific as that airport is absolutely enormous). WiFi was NOT engaged.

Hi guys, I think Verizon is now offering domestic HSPA roaming on T-Mobile on devices lacking CDMA. While looking on Verizon’s international coverage map (https://www.verizonwireless.com/wcms/overlays/international-travel-coverage-map.html), I noticed 3G coverage in Curlew, WA which only shows up when “World Device (with GSM)” is selected. The coverage is not there on the “Non World Device (CDMA Only)” setting. Upon poking around the source code, I found that map loads several coverage layers, including one called “directumtsamericas”. Upon cutting out all of the layers barring this one, I found that the map exactly matches T-Mobile’s HSPA coverage map. It is interesting to note that UMTS-only (non-HSPA) areas on T-Mobile’s map do not show up on Verizon’s map I know Verizon has offered UMTS roaming for CDMA-less devices on AT&T in the past. Maybe they are now replacing this with T-Mobile roaming? EDIT: Premier sponsors can now view this coverage on the Ultimate Coverage Map.

So after finding the perfect spot(only took me a month haha) I'm now getting great results! 13/3 now vs 1/0 old.

1X800 slowly turning on in North Corona. Some sites are still on 1xRTT down south Corona. Pretty excited as this will help with a lot with battery life

Received my g3 magic box and now I can get service in driveway. Small victories can save a day

Looks like some one is having a good day,

🔥🔥🔥 .... Wow....

I was getting 14Mbps downloads with WiMAX which was about equal to most LTE at the time. Dramatic improvement over 3G. You can argue it was a waste of money because it was an evolutionary dead-end, but the licenses were use it or lose it. It was the last major site expansion for Sprint. You could also talk and use data at the same time (WiMAX and Wi-Fi shared the same circuitry, 3G was separate). My current phone is capable, but has not seen VoLTE yet. lol.

Dr. Saw with the shade.... 😎

LTE B26 in Corona near Magnolia and Fullerton. Noticed my phone was on 3G, toggled airplane mode, connected to B25, should be in B41 cause have a MB at home, went upstairs where the MB is installed and saw it was working fine (had to restart MB already twice since I got it cause sometimes it looses LTE), checked my phone again and boom LTEB26 Was at AMC at Tyler Mall over the weekend, inside the theater saw the B26 for a second but wasn't able to grab a screenshot and then it parked on B4 Roaming on T-mobile so I knew it was coming.

VoLTE will always work fine as long as RF conditions are sufficient for a 12.65kbps data session. QoS takes congestion out of the equation. Your experience on Calling Plus is not at all indicative of the experience on VoLTE. To give a personal example, Calling Plus never worked at football games for one of my friends but VoLTE has no issues at all.

VoLTE should hit the Pixel 3 soon. So that's something.

Yep! Enjoy that 15+10 B25 network

I saw this on my Google Now feed yesterday and thought it was awesome: https://www.phonearena.com/news/Former-NASA-engineer-packages-4-LG-G5-to-create-the-ultimate-prank-for-Amazon-package-thieves_id112059

https://www.wmata.com/about/news/Metro-AT-T-Sprint-T-Mobile-Verizon-Wireless-announce-milestone-in-tunnel-wireless-coverage.cfm “Today Metro and the nation’s leading wireless carriers, AT&T, Sprint, T-Mobile and Verizon Wireless announced that more than half of Metro’s tunnels are now wired for cellular and data service. The milestone was accompanied by the formal announcement of three new tunnel segments coming online as “wireless ready.”” The three new “wireless ready” tunnel segments announced today are: • Blue/Orange Line between Ballston and Rosslyn (5.6 track miles) • Blue/Orange/Silver Line between Rosslyn and Metro Center (4.8 track miles) • Green Line between College Park and Fort Totten (7.4 track miles) ——————— Progress! New segments are coming online as the work is finished. The Press Release says they’ll be done by Mid-2020.

There's actually 2 firmwares in the unit...the top number starting with 15.x is the UE relay firmware that downloads from the network when the box connects to the tower...the bottom number starting with 60.x is the firmware on the box itself for the UI, networking wifi and Linux OS....let's report both when sharing

The deprioritization level is also 50GB now, so that shouldn't matter at all.
