    The Best and for Cheap

    Swapped from Cricket mobile to Ultra and I'm having a better time with Ultra. They have superior customer service and I can contact my friends in other countries. I would recommend Ultra to my friends and family.

    Affordable and nice

    Very affordable and comes with unlimited talk and text. Thanks Ultra

    Ads sent me to Ultra

    I saw lots of ads for Ultra Mobile on Pluto tv (iirc) and decided to give it a shot. It is a little more expensive than Mint Mobile but it's also much faster. I think I'll stick with it.

    Ultra by T-Mobile

    Has a good signal for a T-Mobile service. Worth every penny I paid for.

    Mint's so much better

    Ultra Mobile's garbage. It's a ripoff for the same service as Mint.

    Pretty good

    Sometimes data doesn't work but it's overall good. Does the job if you're traveling in the US.

    An ULTRA good network

    I really like Ultra Mobile. The SIM card is so easy to install and activate and you get fast internet and I get 5 bars no matter where I go. It saves me a lot of money too. I left Verizon for Ultra Mobile and I'll never look back.

    Great!

    UltraMobile offers great pricing for their plans. Easy to activate .

    Works most of the time...

    The Ultra Mobile app works most of the time but sometimes it stops working. The only fix is to uninstall and reinstall. When it works it works great.

    A great value.

    Ultra Mobile has great coverage for my phone for cheap and offers unlimited International Texting to over 80 countries which I absolutely need and love because I have a lot of family members outside the US.
