Cricket Wireless IMEI checker*: https://www.cricketwireless.com/cell-phones/bring-your-phone

Verizon Wireless IMEI checker**: https://www.verizon.com/od/prepaid/bring-your-own-device/#/deviceDetails

*AT&T no longer has an IMEI checker on its website, but they own Cricket Wireless, which does provide one, and uses AT&T’s network.

**For Verizon, you can skip the make and model info; then choose “I’m not sure” for the question about where you purchased the device.

This also applies to all the MVNOs that run on the above major networks.

They run their own independent network in a limited geographic area of the US, so they’re not an MVNO, but see this for more info: https://bestmvno.com/mvnos/us-cellular/

Sprint, now owned by T-mobile, only allows an approved list (https://sprint.com/landings/bring-your-own-phone/index.html#eligible-device), or else diverts to T-mobile’s site from this landing: https://www.sprint.com/en/landings/bring-your-own-phone.html.

T-Mobile’s IMEI checker doesn’t work. When I click “Check phone”, it shows a rotating circle thing that never stops.

I just checked my IMEI and it works fine for me. Is it possible it’s a browser issue? Are you using NoScript and maybe forgot to allow the necessary items to run?

By the way, @everybody, in case you’re wondering, only T-mobile’s IMEI checker approves my BM818-A1; none of the others do.

No, I even turned off the ad blocker.

But just now, I deleted cookies for all t-mobile related domains, and then it did work. I guess they have buggy cookies.

I set cookies to always delete on exit, so maybe that’s why I didn’t have the issue.

Even if the librem phone is compatible with Verizon it still WILL NOT work for phone calls. Only when or I guess if purism gets it registered for volte (or even gets volte working in general for that matter) will it work. Texting probably won’t work either. Sorry if I sound aggressive, I have just seen way too many people who blindly believe that if the lte bands match, then the phone will automatically work on Verizon. Verizon is an *sshat when it comes to phones that they can’t inject and malwareise with their bloatware.

Or when Broadmobi does, actually, since it’s the modem that has to be tested and certified, if it hasn’t been already. (It apparently has been with T-mobile.)

Currently of the 3 major carriers, T-Mobile is the only one that supports the BM818 modem. The Cellular Providers · Wiki · Librem5 / Librem 5 Community Wiki · GitLab wiki page is very out of date.

I recently changed from AT&T to Mint Mobile (a T-Mobile MVNO) on my L5. The BM818-A1 was working fine on AT&T.

Odd, spent about 6 hours trying to connect to their data network. The minute I enabled VoLTE, I received a text from AT&T that said:

Hi, it’s AT&T. The device you tried to activate does not work on our network. We’re here to help. Go to Learn Why Some Devices Don’t Work on Our Network - AT&T Wireless Customer Support for more info and learn how to stay connected.

I have a Librem 5 USA, which also has the BM818-A1 modem, so maybe your phone was grandfathered in and they disallowed any new ones connecting to their network?

It could also be that my SIM card was active on AT&T’s network using an Android phone before I moved it in to my L5.

Same, mine was active in my Galaxy S8 until I started randomly getting hit with “No SIM detected” errors after being on for 24+ hours.

I was able to get to an IMEI check on the AT&T website through Let's identify your device - you just select a plan first then enter the IMEI. The one I put in for my L5 USA is definitely not supported.
