Call customer service and have your phone replaced. It might be faulty. Mine works with T-Mobile and AT&T - both GSM. I don't think it works with Sprint since they use CDMA network.
Sorry, there was a problem. Please try again later.AT&T has a short list of phones that it will allow to work on their network right now. Do even though the phone is fully capable it may not be allowed to work. Check their website for the whitelist of working phones before purchasing, or switch to a company that cares about their customers.
Sorry, there was a problem. Please try again later.Yes, the OnePlus 8T 5G will work with both At&T & T-Mobile. I am running dual SIMS and have both. HOWEVER, I just got off the phone with AT&T earlier and they do NOT support OnePlus phones as far as offering 5G even though these phones are 5G capable. They want you to buy THEIR phones that are locked to them and filled with their bloatware. T-Mobile supports these phones and has great 5G coverage in most major metro areas.
Sorry, there was a problem. Please try again later.No, 8T works with TMobile. I'm using it
Sorry, there was a problem. Please try again later.Yes most unlocked phones work with global industries like T-Mobile otherwise when you look for unlocked you want to look factory unlocked meaning your carrier specifically unlocked whether it be Verizon T-Mobile Sprint etc but there is a long list on there like TracFone cricket T-Mobile and I know first hand from the original OnePlus 8 that came out worked on T-Mobile Verizon page plus and TracFone no problem. I'm hoping it will work on other subsidiary companies as well
Sorry, there was a problem. Please try again later.I've never heard of the OnePlus 8T + But there is a OnePlus 8T + 5G, the plus means (and) It worked fine on AT&t and all carriers, check for the all antenna bands that it supports. Could it be possible that you accidentally carrier locked it?
Sorry, there was a problem. Please try again later.Hi! Don't understand what you mean that phone doesn't work with these providers. I have a one bought one month ago and works normalny, so far, with ATT. Don't know what happened to your phone? Is there some error or sth?
Sorry, there was a problem. Please try again later.This phone works with all the careers if you are buying an international version of it. as it is GSM + CDMA compatible. First of all, there is no OnePlus 8T+ phone. OnePlus 8 Series have only 3 phones, OnePlus 8, 8Pro, 8T. I am using this phone with AT&T and an international Sim(Vodafone) and it is working perfectly fine without any issues.
Sorry, there was a problem. Please try again later.
