My neighbor mostly uses her cell phone and is thinking of dropping her landline, but is hesitating because she has had this number for many years. I suggested porting her number to GV, but I have a question. The recommended way is to get a pay-as-you-go T-Mobile account, port the landline number to T-Mobile and then port T-Mobile to GV. Now it looks like T-Mobile doesn't offer the pay-as-you-go accounts and only has monthly accounts. Is there another cheap method to port a number to GV? The other option is to port to an SIP VOIP provider and pay a few dollars a month.
