Customer Ratings & Reviews

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.

East to start and Activate. Good network coverage in our area.

I have used Ultra Mobile since 2012. They offered an excellent service; I have never had coverage problems at all along the East Coast from Maine down to Florida. I really recommend their service

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.

The product value and cost meet and met my expectations.

They have good plans that fit your budget. The service is good.

I got this one after my phone purchase , it gave me opportunity to call internationally + best data plans ,no high monthly data payment plans.I’m using it for more than 3 years and no issue for me at all.

Sim card works great, be aware not all models of phones support it. Check their website to make sure it supports your phone.

extremely good and reliable,i currently use it as my cell phone plan for 15 USD a month, so I can have the option to upgrade to a 60 USD a month plan to have internet wherever with no data limit if I need all of the sudden,extremely good

It's good when you need a carrier or phone service on the go.

Fast, smooth installation and very nice prices for pay card

I really liked this Sim card. I bought it for my parents, who are staying with me for 2-3 months. Other mobile carrier plans were too expensive and they even didn't seem interested to give me such sim or bother about explaining about plans. This Ultra Sim: You just have to buy it, activate it on your own phone, choose the plan and pay and there you go. My parents receive and even place outgoing calls to India without any hassle. And reception/ signal is also good. Totally hassle free..!
