I’m currently Indonesia and Eight mobile does not allow me to call out or receive call. I saw the roaming list it mention that there is no VOLTE. Tried to disable VOLTE but still not working. Anyone knows how to fix this? Meaningless if I’m not contactable in countries that don’t support VOLTE
can use apps like WhatsApp to call?
(i know it won't work with banks, govt/official agencies)
that's where telcos with VOIP apps are useful (eg Simba, MR). they work even on data/roaming connection from other companies. I'm not promoting them, just giving an alternative.
(Or sign up with VoIP company to have a "roaming" VoIP number)
unconditionally forward your eight number to whichever VoIP number you subscribe to, and can receive calls anywhere you have a data connection.
if the above are not an acceptable solution, then no choice, have to port out.
