Customer Ratings & Reviews

There is issue in SIM, I'm not sure why it can't be used for Whatsapp application. It's throwing the error.

The card cannot be used. I tried everything and even call it to the Ultra company, however, Ultra said they didn't have this card so they cannot provide me any help.

I purchased this SIM card on August 2023, but the activate by date is February 2023, already expired 6 months. I called them, the customer service asked me to contact Ultra. Very bad experience with Best Buy.

Not good service. Data ran out quiet fast. I was not happy at all.

I already activated it but i cannot use mobile data and cannot use to text message. Why?

Makes it seem like the card can be used internationally and it can't. There is not unlimited calling and texting internationally that part is a lie.

I used this card when I was in Canada for Whatapps and checking emails. Not sure why it only last less than 1/2 day for 2G! No worth for the $!

Great plans for calling international destinations

I bought 3gb pre paid SIM card,but received 2gb sim card

They sent me a card with 1 GB instead of 2 GB. Can't return it because I need it now.

Very good deal. Excellent service for a cheap price.

Good product, easy to setup and no credit card info involved in the setup process.

just put it and works perfect. My parents visited just for a month and needed wireless service a month. Not require any information just working once you put it in to cell phone.

purchased this for my mom who was visiting us. The process was very easy, just had to ensure my mom's mobile was compatible and then the activation process was intuitive. The signal is great, no issues with mobile data as well.

Works great and super fast setup! Unbeatable service for the price.

First one I purchased couldn't be activated. When I called Ultramobile, they stated the sim was activated in August. Did an exchange only to have the same issue but activated in September. To add insult to injury, the manager at the store gave me attitude like I was some sort of scammer when I tried to exchange for a different prepaid. Safe to say I would not be buying anything from that store again.

I would have given it 0 stars for the review but had to put at least one star. It was very complicated on transferring the service over and per instructions if I wanted to have calls to my same number while in Mexico for the three days I was there I had to input my current cell phone number while setting up the SIM card for use while I was there. I purchased the unlimited text, talk and data plan and when I got to Mexico it worked sporadically, mostly the first day. Afterwards I wasn’t able to order an Uber or text or make phone calls. When I called customer support I was told I had to pay extra roaming charges which still didn’t explain why I couldn’t send or receive text messages. Upon my return back to the US, even though it only worked a few times, Ultra wouldn’t refund or give me any credit. This is the worst service and coverage. If it wasn’t for my daughter’s phone I would have been in another country without a way to make calls, text or obtain Ubers as needed. Very unreliable and no peace of mind for travel. When I went to put my other carrier’s SIM card back in my phone, I learned that the instructions given by Ultra to simply use my phone number while in Mexico moved my number from my original carrier and gave it to Ultra. It took most of my day when I returned to get it straightened out and get my number, which I’ve had for over 20 years back from Ultra and back to my account with my carrier. What a nightmare! Do not waste your time or money with this product or company!

Very easy to use. I put the card in, and it was working in 5 minutes. I bought it for a trip to America. If you want only one month like me, don't put in Your credit card. When getting my phone number in my country it took hours.

I purchase the plan directly from Ultra mobile. I activated the service for a 2 gb plan of data on Monday afternoon. By Wednesday, I have used up 48% of data. I am not a heavy user on the 2 and 1/2 days of service, Its was light usages, checking email, looking up things, and sending 4 pictures, no YouTube or any video or maps. I was home using wifi most of the time. With my old services, my data usuage is usually around 2 gb of billable data per month on a unlimited plan, the reason for the switch. I called customer service, they said it was normal, no issue there. They said it could be me not knowing I was not on wifi or my background apps refresh often. I don’t use my phone that much at home, I use ipad and computer. Used up 1 gb in 3 days and no video during the usage is ridiculous. I will looking for some other company or switching back soon. Not happy at all with this company. Something is fishy here. With the way the data is being used, I guess I may need to upgrade to a higher data plan or unlimited plan. I guessed that’s how they get you.

This sim did not work in the One Plus phone. I would get internet and text, however no incoming calls were avle to be received.
