1Mobile isn't "intrusive " at all. I've been using it since we could use it and I've never had an issue, like many others. It's easy enough to turn off the notifications, not a big deal.
1Mobile has a better selection than Amazon and doesn't require Side loading like Snap.
Sorry for the argument but this one has been discussed in:
