The OnePlus 6T is the first device from the company to be available in the US via a major carrier. OnePlus snagged a deal with T-Mobile to release its devices in the US and this seems to be working out really well for OnePlus.
T-Mobile has just released an update for the OnePlus 6T which enables support for additional domestic roaming partners. The update build number is A6013_34_181228 and does not bring along any other changes or fixes for the device — at least as far as what T-Mobile revealed.
The new update should finally solve a major issue regarding the loss of network in some regions in the country due to limited carrier support. So if you’ve been having network issues while on roaming with the OnePlus 6T, then things might change for the better by installing the latest update.
This update is specifically for OnePlus 6T users who picked up the device from T-Mobile and would not be available for any other variant of the device. According to the carrier, the update was made available on January 3 this year and should be available to download via OTA.
If you haven’t yet received the update notification on your OnePlus 6T, then we’d suggest checking for the update manually by heading over to Settings > System > System updates.
