I have a T-Mobile prepaid sim plan that I had for over 15 years. Balance on the plan can be renewed for as little as $1 for another year, e.g. with a balance of $315, by adding $1 on 4-2-26, the new balance will be $316, and the new expiration will be 4-2-27.
Phone plan is a Legacy Pay as you Go-- Phone calls are 10 cent per min nationally, Text are 10 cents per text nationally as well
The account has $316 or (3160 minutes available) balance which can be used for call or text only. The balance on the plan has an expiration till 4-2-27 which can be renewed for another year for as little as $1 as described above.
The sim can be inserted to any T-Mobile carrier or UNLOCKED phone. This sim also has an assigned phone number to it already as well.
This type of phone plan is very suitable for elderly who needs a phone for emergencies.
