Recently bought a Mudi router after seeing it recommended for GrapheneOS users around here on SN. One thing I've seen a few people mention is that they use a pay-as-you-go SIM in the router and never put one in the phone. What are some good SIM cards where I can:
- Prepay so I can switch them relatively frequently (GrapheneOS users -- do you actually do this? Does the cost of doing so add up?). I'm only really finding things like "Pay X amount per month for Y amount of data".
- Decent speed and coverage (currently in US).
- Pay with Bitcoin...? ;)
I'm doing this partially because I've seen posts where people say you should separate the SIM from the device. why does this make a difference if presumably the router is going everywhere with me just like my phone? Any other tips for using this in a privacy preserving way?
