Hi there, I may be beating a dead horse, buuuut still looking for some help. I have a factory unlocked iPhone 6 that I use for traveling, which most of the time is in Ethiopia. About 8 months ago, they switched on LTE, got my sim upgraded and it worked great for about five months or so. At which point, I somewhat stupidly signed up for the public beta versions of iOS 9, which promptly shut off all LTE. Initially, I figured it might be a bug in the beta, so left it, but I've never been able to get it back and working. A couple of other data points: - I've tried the sim in my iPad, gets LTE fine, so doubtful it's a problem with the sim. - I'm on Carrier 22.0 - I've put in a couple of foreign sim cards, trying to a signal here that is roaming, while connected to wireless in the hope that it would force a carrier update that would bring back LTE, but no dice. - I have experimented with various settings under the 'LTE APN' under cellular data, you guessed it, also no luck - Ethio Telecom is not an Apple Supported carrier, but seemed to work fine four-five months ago. Any thoughts, ideas, knock-knock jokes or helpful suggestions welcome.
