Sim cards and carriers, discussion

[calinb]

Wonderful! Glad you found a solution.

Thanks, rocket2nfinity! It's been a long and sporadic research project and much of your work here has been most helpful to me.

My white SIM card has been working great all around my neighborhood all day. I've tested inbound and outbound SMS and voice calls and I was able to setup voice mail with a nice and stable voice connection for the entire process. It's funny that the solution turned out to be the white SIM card that US Mobile doesn't even recommend for my zip code. Imagine that. It's the opposite of what the cell providers usually try to sell rural customers (optimistic maps and wishful hope-ium)! On the other hand, the US Mobile-recommended black SIM would not be terribly useful in my area with any phone, due to the Verizon / Inland roaming agreement and the additional roaming charges imposed on US Mobile customers by the deal. Inland also throttles data to roaming phones at "1x" or "2x" speeds

Resurrecting a subject we've discussed in the past, the US Mobile white T-Mobile network SIM card supports VoWiFi. The US Mobile chat support rep told me their black Verizon network SIM card will support it soon. Of course it's promoted as a service for Android and newer iOS phones only. Do you know if this is a SIP service? It would be nice to be able to take advantage of it on the Pinephone. I just got my Pinephone "phone" working but I'm already getting greedy for more functionality!

My advice for anyone planning to give US Mobile a whirl is to make sure you get the dual SIM card kit and don't rule out trying both SIM cards.

Oh...following your lead in your post above, for US Mobile white SIM, APN is pwg:
