Today in the "buyer beware" category, the Mobley device is being offered on a limited-time low-priced promotion. It's a popular cellular internet option among RVers.
After watching Technomadia's January 23, 2019 distillation of this newest offer, my husband and I decided to try it. I have Verizon, so we added it to my husband's AT&T account, to give us better coverage in Verizon's well-known Texas whiteholes (in east and south-central Texas).
About 48 hours after the Mobley was delivered to us, and
before we even had an opportunity to activate it, my husband got a text message from AT&T informing him that he owes over $1,000 in international roaming charges.
AT&T confirmed over the phone to him that those charges are real.
In other words, the Mobley was delivered to us pre-loaded with massive debt.
We are still working through the resolution of this. Apparently we are among the first to report this scam, because when my husband began the process this morning, AT&T sounded clueless (he had a CSR on speakerphone).
I've alerted Technomadia and we are all standing by to learn more about this. Meanwhile, here is their explanatory video of two weeks ago. The Mobley is potentially a good cellular device if you can get it and operate it without getting scam-screwed in the process.
