welcome to iSIM - Currently my GSM provider pick. I just love when things change, especially if it's for the better. As time passes there could be better deals.
Virgin mobile is also a good option if the mobile is used more. Calls from Virgin home phone are free and the rates are great. The only drawback is that the $25 credit expires in 45 days. So, if the phone is used it's worth it. Otherwise, use iSim or SavvyTel to have a pager and an emergency phone access. :)
