Well, as I feared, the Karma Go wifi hotspot will not work for us at Riverview. The Sprint network, which they piggy back off of, is spotty at best anyway, and a look at their coverage map shows it dancing all around us yet skipping over our precise location so completely. I tried repeatedly to move the device all over the house to pick up signal, and I actually briefly did in the munchkin's room. By the time I walked to the iMac in the great room to see if the Karma option populated in the wifi networks drop down list, however, it was disconnected and showed only the green battery power light. C'est la vie - I knew it was a hazard going in.
We do have a pre-paid month of unlimited wifi, however, so I'll take it and use it with my laptop in town to really test out its capabilities all the same. I think I will discontinue the Neverstop plan but keep the device and reinstate it once we start traveling. A rep said the plan automatically reverts to the Refuel option at the end of your prepaid month if you cancel the auto-billed subscription, so at least it'll be easy to pause until we head out.
Now, however, I still need to find an alternative and less expensive internet source. I can't sustain a cell bill larger than our truck insurance and more than half our monthly lot rent! I'm thinking a T-Mobile unlimited plan with the cheapest phone they have will be my next try, and if that doesn't work it'll be on to AT&T.
Any other suggestions?
