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.

    Best option for a tourist. My mom was visiting from overseas and this product was enough for a 2 weeks visit. It worked just fine.

    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.

    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.

    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.

    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.
