Take this with a grain of salt, but I have a friend on AT&T who is experiencing the exact same thing. She only uses HSPA because she thinks LTE drains her battery (have tried convincing her otherwise many times...) and she can't even get an iMessage to send on "4G".I am referring to the data network. HSPA network seems to be crawling, and I can't get anything more than 10mbps with LTE. We have band 17 (10x10), band 2 (10x10) and band (5x5), yet these issues occur.
AT&T's band 17 and T-Mobile's band 12 are alike... But... T-Mobile only has 5x5 band 12, so you won't get great speeds. Plus band 4 has priority over band 12.Att has been very good to me. The only issues I've had are in certain buildings. I'm starting to wonder if T-Mobile is better because off all the new/updated towers they have been implementing?
Here in Metro Atlanta, AT&T and Verizon basically have parity in terms of coverage, in my experience. LTE throughput obviously varies by location but I'd give AT&T a slight edge in most cases based on my experience with both carriers. I haven't tried T-Mo and won't go near Sprint. I'm liking AT&T more than Verizon currently because we have a 24% FAN discount on data with AT&T compared to the 6% discount we had with Verizon.Why do I feel AT&T service is declining? Any other iPhone users experiencing issues with AT&T? Their service in my area has always been exceptional up until recently?? Perhaps the network is getting too bogged down, i don't know.
Sprint's WiMAX network is essentially dead: http://www.fiercewireless.com/story/court-sprint-can-begin-kill-wimax-network-week/2016-02-01
I had T-mobile for 2 years up until a week ago. I switched to Sprint because my job is offering a 20% discount, but T-mobile data was very fast here in NYC. Only problem I had was their coverage, especially inside buildings and underground. There are places I get service with Sprint that I had completely no service with T-mobile. But like I said in good coverage areas they are great.Just seems like to me T-Mobile has made drastic improvements in my area and it's much cheaper. I'm considering trying a line out to compare. A few friends of mine had att and switched over and are saying it's better. Curious if anyone has tried T-Mobile or currently have it?
