@notplants This is something that I also deeply want but I kind of suspect that the best you might be able to get is going to look something like "burner phone as a service" and even then it might be hard to keep that going without those SIM cards being deactivated.
@forestjohnson as I continue to research this, it seems like masking up, getting on public transport, and buying a sim card and second hand phone in cash is the cheapest and most reliable way to do this in 2025
I guess technically if someone really doesn't want to or can't leave the house, asking a friend, or finding a stranger on the internet to help with this and paying them via xmr, is also possible. I stumbled across xmrlance but it appears inactive
also found a number of sim card suppliers that accept xmr here https://app.monerica.com/search?q=sim+
so using one of these + some method to connect a sim card to laptop and send/receive text from there might be a good route to doing this without leaving the house (but I am still unclear on the details of this last paragraph and how to do it -- curious for a guide on this)
also for true anonymity, probably better to keep the simcard disconnected, and do account activation with the anonymous sim at a coffee shop etc .and not at home
