I have questions about prepaid plan and regular plan
I'm trying to use a service for only a month. Is it possible for both prepaid plan and regular plan just using one month and stopping service? and do I have to pay some fees if I stop my service after using only a month?
What's the differences between the regular and prepaid plan? Is it for prepaid you pay before you use a month and for regular you pay after you use for a month?
I see some refill cards on Walmart or Kroger, are these refill cards prepaid plan or the regular plan? I'm thinking about buying one of these refill card and buying atnt sim card. So can I just put in sim card and activate my phone on online using refill cards?
Lastly, does any phone compatible with atnt by IMEI test available for use of all the plans that atnt have? Thank you.
