Fair prices and good service

Straightforward and basic, the SIM card arrived without any problems. The plans are not only affordable but also reliable.

Good service if you've got coverage

I'm really satisfied with Ultra Mobile's service, which offers unlimited national calls and texts at a very affordable rate. As long as you're within T-Mobile's coverage, it's an excellent option for those mainly interested in calling and texting.

Just what I needed at a cheap price

I needed a basic plan with limited internet and couldn't find anything affordable with major carriers, whose plans usually start at $30. Ultramobile offered me a budget-friendly option without requiring a yearly commitment. The only drawback was the lack of choice in selecting an area code or phone number; otherwise, I'd give it a 5-star rating.
