How do I setup my SIM card? SakuraMobile December 05, 2018 09:39 Updated Follow Please refer to our APN Setup page. Related articles I did setup as instructed, but I can not use internet I lost the return envelope. How should I return it? Can I apply the service from overseas? Is activation required for the SIM card? I am currently subscribing retail plans from Docomo / Softbank / AU. Can I move my phone number to Sakura Mobile?
