How to port a SIM card to an Android phone The procedure for porting a SIM card from a pay-as-you-go phone to an iPhone 4 is well documented (example 1, example 2, config tool for iOS 5). This is a nice option for people mostly on WiFi who use a small number of minutes (or VoIP), because with AT&amp;T GoPhone plans, you can keep network costs down toward $100/year.

Is there a similar procedure for porting to a high-end Android phone? For example, can you buy a $3 GoPhone from Best Buy, buy an unlocked or AT&amp;T Samsung Galaxy S II off eBay, move the SIM card into the Galaxy, and expect it to work? Other than ensuring the GoPhone plan has a data bundle feature, what other configuration is required?
If you have an unlocked phone, I don't think there should be any problem. The SIM card for GoPhone is apparently just a regular prepaid SIM card and is not tied to the phone it is sold with. If the phone doesn't recognize the APN for 3G, just go to Settings &gt; Wireless and Networks &gt; Mobile Networks &gt; Access point Names and enter the appropriate access point settings manually.
