Don't like losing my balances

Normally I only need a 2 gig subscription when I am home, because I am using wifi. But when I am about to start a trip, and I want to be sure I have mobile data, so I need to sign up for 5 or 10 gig. If I renew, I lose whatever balance I already paid for. Tello should roll the unused portion into my new plan. I would be ok witha limit on rollover balances, say 2 gig or 5 gig, but having rolloverst would go a long way toward improving customer satisfaction.

Affordable Prices with Less Stress!

I've been with Tello before in the past and then eventually moved to Other carriers, only to return. My mom is even on Tello because its affordable and you buy what you need and what you could afford. There's few other carriers similar to Tello and I checked them out but Tello really is Truly Affordable, with less stress.
