#Phone #number for #SMS verifications, Sim Services and more.

Recommended: Providers which accept Monero (XMR) and don’t require verification:
(Iceland based) https://crypton.sh [Tor Mirror] [Archive.org]

(Ukraine based) https://virtualsim.net/ [Archive.org]

(Many countries) https://silent.link/ [Archive.org] (my favorite)
Do require e-mail verification, but accept Monero:

(US California based) https://mobilesms.io [Archive.org]

(Germany based) https://www.sms77.io/ [Archive.org]

(Russia based) https://onlinesim.ru/ [Archive.org]

There are some other possibilities listed here https://cryptwerk.com/companies/sms/xmr/ [Archive.org]. Use at your own risk.

Now, what if you have no money? Well, in that case, you will have to try your luck with free services and hope for the best. Here are some examples, use at your own risk:
https://oksms.org
https://smspva.com
https://sms24.me

Disclaimer: We cannot vouch for any of these providers. We recommend doing it yourself physically. In this case, you will have to rely on the anonymity of Monero and you should not use any service that requires any kind of identification using your real identity. Please do read Appendix B2: Monero Disclaimer.

It is more convenient, cheaper, and less risky to just get a pre-paid SIM card from one of the physical places that still sell them for cash without ID.
