## Description

desertcart.com: Prepaid SIM Card (US Mobile) - Custom Plans from $4/mo. Unlimited Plans from $17/mo. : Cell Phones & Accessories

Review: Great Sim card kit for US Mobile - US Mobile SIM Card kit contained cards for both ATT and Verizon. Cards were also adaptable to all 3 standard size SIM cards. Easy to setup and worked like a charm. Thank you desertcart. Received the kit in one day and this was truly a blessing because US Mobile botched my order and ultimately took 14 days to deliver my cards. I was panicking after 2days without a phone... That's why I ordered from Old Faithful: desertcart. Finally, you won't find this kit for a cheaper price anywhere on this Planet.
Review: Good choice for the budget-minded - I've had US Mobile service for over 3 months now. I'm on their GSM 2GB Share Plan which includes hot spot and unlimited calls and texts nation-wide, and from within the US to Canada, Mexico, and 86 other countries. Call quality and connectivity is solid in cities. I can't speak to rural areas, though I've read that rural connectivity is almost non-existent when on their T-Mobile connection. Apparently, their Verizon connection is better if you live in or frequent rural areas. I'm mostly in medium to big cities on the East coast. Data speeds are decent/good during peak hours (according to my research, they get better priority compared to other MVNOs) and great during off-peak hours. I'm on their T-Mo connection and is on par or a little better compared to Mint Mobile during peak, and downright great compared to ATT prepaid in my areas (mainly East coast, some West) whether on or off peak. ATT cannot compare to US Mobile. It's amazing that ATT charges more than double for their annual prepaid plan for subpar service. Two negatives: They took almost two days to port in my number from ATT. In this day and age, ports should be completely automated and happen almost instantaneously, or a few hours at most, not days. CS rep responded quickly enough to my inquiry, but just gave a generic "they ran into issues during the port process" response and did not provide any kind of specifics. But at the very least, they responded quickly and were aware of an "issue" and were actively trying to "resolve" it. The port went through about half a day after I contacted them, and my service was active and ready to go. The other negative is their voicemail system. It requires you to actually say something on your outgoing message. With every other VM service I've had, I could choose to have the system give an entirely automated generic message akin to "you've reached [phone#], leave a message at the tone". But with US Mobile, you have to have your actual voice on the outgoing message. Not that it's a big deal, but I just prefer a completely automated message rather than my own voice. I won't deduct any stars for the couple of negatives. The two days wait wasn't too extreme (especially for the cost-savings), and the voicemail thing is just a personal preference, nothing to do with vital functionality. These are just some things to be aware of. Good choice for budget-minded folks who don't always need the top most data priority/fastest speeds during peak hours, but enough to surf the web, check emails/social media, pretty much everything except streaming UHD video.
