I split my time between UK and Japan, and as recently as about six weeks ago could use GG sim to send (and receive) texts in Japan. I'm guessing that voice calls would have been OK, too, but never used it at a quid a minute... Could log on to GG with both NTTDocomo and SOFTBANK networks, no bother.
Tried yesterday using both the same phone as last time and a couple of others but could not connect to GG though I could get the phone to connect to NTTDocomo and see the "R" roaming symbol. Previously the phone displayed the GG roaming welcome message but no more.
Has something changed with GG in Japan? Again, up to last month could connect, now cannot.
Is there anything else I could try?
(I have Japanese mobiles, mobile and fixed wifi, this is only for sending/receiving UK texts to my GG number.)
