Can I get an AT&T pay as you go plan to work with my legally unlocked 3G iPhone?

Question

I have an unlocked iPhone (I live in a country where it is illegal to lock phones) and each year I spend the holidays in the US. So I want an AT&T prepaid (pay as you go or any other) plan to allow me to use the 3G network and make phone calls when I'm in the country without incurring the highway robbery that is multiple carrier international roaming charges. Does the AT&T pay as you go plan provide a sim card that can work in any sim car enabled phone (especially a legally unlocked 3G iPhone)?

Answer 1

my son was able to use his prepaid cingular sim card in a 3g apple iphone  :D

Answer 2

If the phone is unlocked, you can use it with any service provider. However, AT&T has been know to lock phones once they are used with their service.

Verizon Wireless Prepay Messaging Bundle Available - $10/month for Unlimited Mobile to Mobile Messaging with Verizon Wireless customers PLUS 250 additional messages

# How do I add a Messaging Bundle to my account?

There are 3 ways an INpulse customer can add a Messaging Bundle to his or her account. Here’s how:

1. My Prepay Account online – Register and login and select the Add/Remove Features link.

2. My Account on your phone – Press up on the 4-way directional key and select My Features (Mobile Web 2.0 capable phone required).

3. Dial *611, select Additional Options, then select the option for calling plans and features and follow the prompts for changing optional features.

# How am I charged for a Messaging Bundle?

When the Messaging Bundle subscription is added to your account, the monthly charge will be immediately deducted from your account balance. The subscription and charges will renew automatically every 30 days. If you do not have sufficient funds in your account at the time of renewal, messages will be charged at the rates in your Calling Plan. Once sufficient funds are added, your subscription and charges will be renewed, and you will be assigned a new renewal date that is 30 days later.

Upon unsubscribing from a Messaging Bundle, you will still have use of that bundle until its expiration date. If you re-subscribe before the expiration date, the original bundle will resume and you will not be charged until the expiration date. If you re-subscribe after the original bundle’s expiration date, a new bundle will be provisioned and you will be charged at that time.

Answer 4

You can only use a phone with the provider it was set up for. I can't use my son's brad new RAZR (AT&T) on my Verison service.
