Now lets see what tmobile supports.
Yms Have two of those, and i will say they are trash, slow like a turtle, horrific hardware on that phone. Phone crashes and turns off.
trying to see what other options i have, alcatel is not on my list.
I have the..
VN220
UN220
Kyocera Cadance
LG Classic flip
LG Wine 2 Unlocked Version
None of those seem to work for tmobile.
Seems i might have to try the Shock or something similar.
Just curios what service was the UN220 Made for?
Does the unlocked one work for verizon?
JumptoheavenLevel 5 - Gold Elite MemberMyi did you try changing the apn settings, depending on the carrier?
Jumptoheaven The APN settings seem to be set correctly, I did check each time to make sure it had the correct APN settings and reset the settings to double check that.
Techgen Jumptoheaven Interesting enough , if what they're telling me(T-Mobile Tech Support) is true then that would explain to why there's a 10 second delay for outgoing and incoming calls when using a T-Mobile Sim card on this LG Exalt UN220, and the LG Wine2 Unlocked Version.
They previously had one band in common on the 4g lte network with this phone, for the calling and it was the U1900 which basically allowed for the, 4G LTE band to work.
While they still have a 2g band which they still support for calling and that would explain why when making a call on the 4g network it takes a few seconds before the call can go out , as it needs to find a 2g band to make the call, and the same is true when it receives a call needing to find a 2g band for the incoming call.
While I tested it solely on the 2g band and the calling works great, as it's not switching before any of the calls, as it's currently the only working band on that device for T-Mobile.
They mentioned since the new 5g is out they're phasing away the old U1900 Band.
Now I got to try it on a At&t sim to see if it works.
Oh well that takes care of the LG Exalt UN220, And the LG Wine 2.
Never understood the reason to phase a band away, unless it's costing them to run it, and there's no use for it, or most Customers don't use that band anymore?
mg5077 The AN and UN seems to be the same.
While the UN220 is an unlocked GSM device so it should techinally work.
And I see it has two of the bands that T-Mobile Supports.
GSM 850/900/1800/1900 MHz; LTE Bands 2/4/5/12/25
So even should they stop supporting the U1900 there's the 850, Band 5
Myi I've sold the UN and the AN in the past had had pretty much a pleasant experience with the UN. Almost no issues. A few customers needed their APN's manually updated. However, the AN was terrible. The only carriers they worked with were Canadian Carriers. On LG's site, it seems like both were unlocked and both had the same bands...
FlippyLevel 6 - Platinum Elite MemberSimpleJew Many people that have tried to use the UN with T-Mobile, didn't work. Even though it showed service, they missed many inbound calls and had poor reception. I know many people that tried it and have also tried it myself on many devices. If anyone thinks it okay, maybe they just don't realize their missing anything...? Or its different in rural/urban areas (I am in Brooklyn NY)? Whatever the case may be, Since the device doesnt support VOLTE it would probably be unsopporterd when t-mobile sunsets the 2g service.
Myi You need to install a file explorer which supports root. [Login to see the link] for example.
Go to root\system folder, and copy from there 3 folders: app, priv-app and framework, and one file: build.prop.
Zip all the things you copied and send the zip archive to me.
