I’ve been on US Mobile for several years. You can choose between the Verizon, T-Mobile or AT&T networks. I’m on the Verizon SIM. Yes, you are deprioritized. No, it’s not an issue.

I’ve been very impressed with US Mobile’s support, though I’ve only needed it a couple times.

You have to hold it extremely still. Like mount it on a tripod still.

I’m impatiently watching Solo Leveling. Haven’t read the manhwa on purpose, just so I don’t get spoilers, but the comments I’ve read have me hopeful.
