Found this AT&T LTE roaming screenshot from 2022... Pretty nostalgic with the old iPhone UI. I believe this was because of no VoLTE roaming so calls couldn't go through.

There really needs to be a pinned post on this but what is the cheapest and easiest way to get SIMs on all 3 US carriers? (T-Mobile, at&t, Verizon Wireless)

Remember someone saying there were eSIMs available around $2 for at&t and slightly higher prices for the rest... Obviously I'm aware that I won't get the highest priority or speeds, just want this for basic mapping since I can't afford three seperate phone plans...

CDMA network which was shut down in 2016, Citycell (470-05), found transmitting 4G LTE in Moghbazar, Dhaka. They plan to relaunch in December so this might be preparation for that.

Just got back from the US with a few new phones, so here's my entire cell phone collection! 136 in total - not as much as some people here but I'm proud of it.

Almost all of the phones still work perfectly! Got these cell phones from various places, mostly family members/friends when switching phones or finding old unused phones in their house, and also places like eBay or Facebook marketplace.

I sometimes upload videos of me testing these phones on my YouTube channel called "si7 MAX" if you're interested in seeing these phones working, planning to test and upload every single one after I can get my GSM and CDMA base stations up and running.

How do I recalibrate the vctcxo trimdac value? BladeRF micro xA4 - Accidentally flashed wrong fw image which led to the vctcxo trimdac value being wiped. Tried to get the information but the website doesn't have it. Is there anything else I can do? Pretty new to this(BladeRF xA4)

I was following this: https://www.nuand.com/retrieving-your-bladerf-calibration-data/ https://www.nuand.com/calibration

Unfortunately used -f instead of -l and flashed the FPGA... Using this for a GSM network so now because the calibration is inaccurate my phones aren't registering or working properly with the SDR... Is there any way I could re calibrate it? I've emailed nuand already but haven't gotten a response for a few days...

Payphone with dial tone at griffith observatory in LA, California - Didn't have coins to test unfortunately, it didn't have a number written on it either. Makes sense though since there is zero cell service here.

Free "pay" phone at San Francisco Airport terminal A, they had 2 of these at almost every gate! Rings too, phone number on last slide (newer 650 area code)

Tello (T-MO MVNO) displaying T-Mobile instead on LTE and falling back to EDGE at the Griffith observatory

Taken july 28, prior to the T-Mobile 2G GSM shutdown. Didn't have time to post till now.

Sorry for the low quality, screenshots were shared to me via MMS

HGC Global Communications payphone / payphone booth in HK! Interesting to see since all of the others I've seen were PCCW.

Any idea what happened to A2GC (American 2G Co-operative)? The person who was managing the whole thing seems to have gotten their account banned...

Got CellMapper working on my Bold 9900!

You can't use ota for jad files with Opera so you have to use the williamsmobile.co.uk http proxy to navigate to http://www.cellmapper.net/downloads/bb/0.1.3/CellMapper.cod and then http://www.cellmapper.net/downloads/bb/0.1.3/CellMapper.jad (as seen in the last screenshot). Keep them both in the same folder then use Applications>Files to click on the jad file to install.

If that doesn't work for whatever reason visit both links on your pc, bluetooth the files to your blackberry, move them to the same folder then click on the jad file.

Great use for any BB classic phones, even supports live upload! Not sure if it works though...
