Customers are saying

Customers highly value the affordability, ease of use, and reliable coverage of the 1-Month 4GB Prepaid SIM Card. Many appreciate the included international calling features and the straightforward setup process. While some users experienced compatibility issues with certain phones, the positive feedback on price, data allowance, and network performance outweighs these concerns. The SIM card is frequently praised as a convenient option for temporary use or travel.

    Fantastic service in the Portland metro area and even beyond! Now as for messaging maybe not it can be delayed to say the least with some friends reporting to have received a message I had sent days earlier. I haven't tested this. My guess is maybe its slow but most likely operator error on the received end. Cheapest service that was out performing "America's most reliable network" in the mountains of SW. Washington if you're on a budget and dont travel much id say this is your cheapest and best choice for service. I can inly speak to the Portland metropolitan area and around lewis falls in SW Washington. Still many other areas that may not be so good but I have yet to test that. On top of that this can be a good way to stay anonymous as there's no requirement for credit cards or adresses, it does however require a verifiable email. Ahem "guerrilla" mail can provide you a temporary email inbox without exposing your information!

    Bought at $14+tax which makes this great value for either a temporary service between carriers or as an intro to Ultra Mobile. Port was easy and almost instant, though I switched from Mint Mobile which is actually under Ultra Mobile. You will need the Acct # and Acct PIN # related to your existing phone service for the port This runs on the T-Mobile network. Data LTE speeds are great, though this particular plan is not for heavy data users at only 1GB of LTE. Have not personally noticed any service issues but may be spotty in certain areas outside of bigger cities

    Data ran out quite fast

    I purchased the card in Best Buy last month. And I activated the service for a 3 GB plan of data. After 5 days, I've used up most of data and just 1.2 MGB left while traveling in Canada. Data ran out quite fast. I was a very light usage, mainly for GPS during days. Without enough data, i can't pay for a parking fee by an app-Blinkay and have to use an offline Map insteaad. That's rediculous compared to 3 GB data in T-Mobiled, in which 3 GB almost last half a month. Soething is fishy over there.

    I've just needed a new phone number. I had to call customer service for some information. They were friendly and did not keep my online forever. On a bad side, it takes about a good 10 seconds to get connected/ They work on T-mobile network which explains slow connection. I would not recommended as a main phone line.

    Recently I frequently saw the ad from Ultra Mobile. So I tried this SIM even the price is greater than others such as Mint prepaid SIM. Put it in iPhone SE2. it is really faster than Mint SIM. Hope the price to be reduced a little.

    Amazing product for tourists. Did not require credit card. Simply swap the sim card in your European phone and go through the simple setup process and it works. My father took it to Grand Canyon and the service was great and 3GB we're more than enough for WhatsApp calls for the month he visited.
