Hi Sheridan,
A few things…
1. Verizon pre-paid is a nightmare!! And don’t even THINK you’re gonna get help from them. I gave up.
2. TMO Gateway is awesome!!!! The add-on, for us, was only $30/month and it’s been flawless for over a year. Not everywhere has good 5G, but I use a backup AT&T special plan.
3. Your experience with the router being rejected is because the carriers now will see the device the SIM is in (via IMEI)…and WILL KICK YOU OFF for violating their TOS, if you don’t have the right plan. This happened to me when I tried to use a Mobley-type SIM a while back…it’s a random thing, but their software is getting dialed-in to be a better hunter. I know the guy who wrote the software for the carriers to block devices.
4. Remember that “unknown” devices will, almost always, get de-prioritized service. For example, IF Verizon detects a device that’s NOT one sold BY Verizon…they’ll bump it down. Basically, a Verizon iPhone gets the top priority, then their iPads, and so on. Again, controlled by their software. Doesn’t mean it’s absolute, but it can and will happen eventually.
5. By the same electronics engineer, he just told me Starlink in-motion is about to get CRAZY expensive. It almost sounds like the new plans will be “Priority” and can cost up to $10k/month for some applications…yikes**. SL was using a speed-check that didn’t allow service over like 8 knots…hence their maritime plan working on boats, but RVs…not so much. So, just keep this in mind. I’d hate you to get a bad surprise…but I can’t see how they could shaft all the “fixed” RV folks. I think my friend told me Mobile Internet Resource just did another update video on this.
**I’m still really unsure of why my friend said the new in-motion Priority will be so expensive. Here is the link for the MIRC video:
Hope this info helps you a bit.
