I switched to AT&T Wireless almost five years ago when I bought the original iPhone. Now, after five years, I will 95% switch back to Verizon Wireless – but not for the reason you think.
Call quality doesn’t mean a lot to me. My area, it works fine and I hate talking on the phone. So I actually enjoy when my calls drop, so I can not have to talk on the phone.
AT&T’s 3G, especially on the the 4S, is super fast 3G. But when 4G comes out, the speeds between AT&T and Verizon should be comparable. It should really put Verizon and AT&T on the same wave length in terms of data and data features (i.e. talking and using data at the same time).
So why am I switching?
I want to unlock the SIM and use it internationally. AT&T will only do it on devices out of contract, which I have plenty of. But they won’t do it on devices in contract. Verizon will reportedly unlock the SIM component when you travel internationally for customers in contract.
I have historically had every single new iPhone that has come out, so if I keep that trend up, I would never have a phone out of contract. Yea, I can take an old iPhone or Android phone and pop in a SIM, but I want my phone with my data when I travel, not a different device.
Oh, and all the other phones on my AT&T plan (3 others) will be out of contract by the time the new iPhone comes out. So leaving AT&T won’t cost much.
