    The Ultra Mobile SIM Starter Kit was very easy to activate and set up. The process took just a few minutes, and the service has been reliable with clear calls and fast data. What I really love is that I can also use it while traveling in Mexico without any issues, which makes it super convenient. Great value for the price and perfect for anyone needing affordable and flexible mobile service. Highly recommend!

    My recent visit to Best Buy was exceptional! I urgently needed a new SIM kit and found their cuatomer service was incredibly convenient. The checkout process was a breeze, and the staff provided outstanding customer service. Plus, I got a great deal on the product a truly fantastic experience overall!

    Bought Ultra Mobile sims from best buy. You can activate any plan from ultramobile.com. Activation is easy. Select your plan, enter in the sim#. You can activate for a new number or port-in your old number. You do need your account# in order to port-in your old number. Activation is quick. Your number is ready to be used in 15 minutes time. If you purchase sim online - it is free but you need to wait 3-5 days to get it. If you want to save time, then purchase sim from a store. Only drawback - you don't have the option to select a number of your choice.

    When I bought this rhe code inside was already expired so I had to do a Esim which was fine since the instructions gor both physical and non physical is on the inside. I have been using this servics for a month now and its not the best I picked 25gb of internet and unlimieted text and talk and im not abke to use the 25gb when ever I leave the house which doesn't help since I'm a content creator and need access to internet on the go.
