Hi everyone, I take about only 2 or 3 calls a day and never texted but BIS's very important for me. I want to ask you guys about which plan of which carrier is the most suitable for me?
Thanks for your advise.
I am not sure about the BIS question unfortunately, but I know ATT will tend to subsidize your phone more than T-Mobile. Example, look at the Bold 9900, on ATT its a $200 phone, on T-Mobile its $300 with contracts respectively.
Although T-Mobile will give you perhaps the cheaper monthly plan though and more for your money over time.
If you're in the US, you're better off going with the carrier your phone was designed to be used with. For example, if you have a T-Mobile 9900, go with T-Mobile or Simple Mobile. (Check out Simple's site. It has a great prepaid BIS service with good prices, and it runs on the T-Mobile network.) If you have an AT&T 9900, go with AT&T. This is the best way to get all features working properly.
AT&T does not currently offer BlackBerry data on pre-paid. So TMobile or Simple Mobile are the options to look at unless you are going to get a contract plan.
