Released on September 19, 2014, this 4.7" screen iPhone is the smaller version of the iPhone 6 Plus. Identifiable by the model numbers A1549, A1586, and A1589.

a1549 won't register with any network

I have one that is stumping me. iPhone 6, a1549, won't register on any network no matter what SIM I use. Tried using a VZW, ATT and Sprint SIM and it wouldn't activate. Popped in a Tmo SIM and it activated. OK...so its a Tmo. I pop a Tmo SIM in with active service and it won't register on the network. Tried rebooting, reinstalling, banging it on the counter, all the usual steps.

What am I missing here? The phone works, the SIM works. I'm half tempted to believe that the phone is locked to some weird network but when I run it through our unlock service, its already unlocked.

HALP?

And just like that...it works. I didn't do anything to it other than open it to see if I could see anything.

I really do hate iPhones.

Hmmm....ran a cellular network test app and the phone isn't seeing any cellular networks. SIM registers just fine, IMEI shows up.

This is an odd nugget.

Hi,

Know nothing about iPhones but thought this may be of interest to you.

Thanks. I'm not leaning towards anything hardware on this one.

Have you checked that it does have the correct time and date????

crwdns2893770:0crwdnd2893770:0crwdne2893770:0

Yea...even toggled auto update and rebooted.

IMEI check came back and its for sure Tmo locked. Sooooo.....looks like it might be hardware.

Don't rule out hardware. Loss of cellular connection is obnoxiously common on the i6. The antenna switch l

(rf5159) has gone out on a few phones I've seen. Any of the antenna connections could be loose or there is some kind of debris between them. Has the phone been disabled and reassembled before?

Never been taken apart, which was why I was trying to eliminate software first. I think I've done that.

Thanks for that part number. Looks like an easy enough swap.
