iPhone 3G on Verizon Network
How can I use my iPhone 3G on Verizon network?
AT&T really has horrible service!
You're right, AT&T has horrible coverage. No, you cannot at this point use it on Verizon, a CDMA technology network (iPhone is GSM). It was almost enough to make me give up on iPhone, but in the end I couldn't do it.
Depending upon your area, other GSM networks might be a solution for you if you are willing to jailbreak and unlock your iPhone. T-Mobile in the US was good when I used it; there are others in Canada and elsewhere.
No. While Verizon is transitioning to GSM and eventually killing off CDMA, many of the early phones rely on CDMA for voice purposes. This isn’t as bad on later phones, so you have a wild west of phones that will eventually be shut out when that day comes and nobody will know unless the model is known to be blocked from activation.
Phones like yours only support GSM so you cannot use it due to technological (and policy) reasons. The Verizon whitelisted 3G phones only use GSM for international use; domestic data is all CDMA. Most (but not all) 4G LTE phones are entirely GSM based with zero CDMA hardware.
Along with technological issues, you also have issues on the back end. Verizon only allows certain IMEI/ESN ranges on their network. The issue is the Verizon programming is hardcoded in a way it can’t always be changed depending on what phone you have. It was this specific issue that forced them to have such a policy.
That said, sometimes you could get the MSL and change it, but that isn’t always the case and carriers do have a habit of fighting to keep the MSL to themselves. Your phone is NOT certified for their network.
I am now considering a Motorola Droid as an option since I am on Verizon and have a couple of upgrades due. Any comments on the Droid as an alternative to the Iphone?
For the record I will also suggest T-Mobile, they have the best prices, the fastest network (both in the US and worldwide) and great coverage. They also have a plethora of android phones, and seem to be getting the Nexus One (HTC Passion).
Yes, but mifi will not allow conventional cellphone calls.
You need to unlock your device to access other carriers. Currently this requires baseband(known as modem in the settings->about tab) 05.11.07 which came with firmware 3.1.2. In approximately a week with iPhone OS4 comes out, there should be an unlock solution for the newer 3.x models also. To obtain this Google the iPhone-Dev Team blog as I'm not sure if I'm allowed to post links here.
Hope I helped!
