Been using it for about five years now. I absolutely love it. But I will say some of these comments make it sound like it’s a little easier than it is. I’d say about 80% of your knowledge from Android will transfer over and just work. But the last 20% is a bit of a learning curve, and will take at least a few weeks to get the hang of.

What I recommended to some of my friends that switched is to get the phone and mess around with it for a few weeks before you switch your sim. Then you’ll get the hang of things like alternative app stores and sandboxed play services, and you’ll figure out what you can and can’t do.

I will say the vast majority of things do work easily because of protection compatibility mode and sandboxed play services. But there will be some things that are just more hassle then they’re worth. I find keeping a second device, like a tablet, without a custom ROM makes that stuff easier.

And there are some things that seem impossible to get working properly, at least for me. For example, casting to a TV is basically impossible from what I can tell. Also, tap to pay, even for things like tickets doesn’t work (although if you have play services, you can use Google wallet for things with barcodes).

Overall, it’s totally worth trying out. Just don’t set your expectations too high. You’re not getting a completely “just works” experience.

As for other custom ROMs, I’ve tried CalyxOS and LineageOS for MicroG. I didn’t find either of them quite as good, but that was many years ago. Maybe they’ve gotten better.

Interesting idea. How easy is it to start and LLC?

I love virtual cards. I use privacy.com for all my online stuff. Not a solution for this purpose unfortunately.

As for your divide-it-up approach, that’s an interesting thought. I guess I’m a little concerned about signing up for several cards with several companies and several privacy policies. Feels a little weird to me, but I do see the merit in not having all your eggs in one basket.

As far as the Apple Card and Goldman Sachs is concerned, I’m still trying to figure out which details are given to whom. Its hard to find info about it. I wouldn’t be surprised if you’re right and it’s the same as any other card from Goldman Sachs.

You can have a primary network and guest network. As far as I can tell, you can’t have more than that.

You can set DNS manually.

Here is a link to a pretty comprehensive user guide that explains all the settings. Maybe I missed something about the SSIDs. https://static.inseego.com/us/download/mifixpro-userguide-tmobile.pdf

I recently got their hotspot and its been good. I got the MIFI X PRO 5G and have no complaints. I can’t speak to the privacy of it, but it uses a T-Mobile sim card. Do you have any questions in particular?
