Long shot here..
I got a viettel simcard under the understanding that I could use the data in cambodia and laos.
Lo and behold I crossed the border into Cambodia after 3 very successful weeks of great coverage and I get the 'emergency calls only' signal.
I gather it's because roaming was not enabled on my sim. Is it possible to turn this on somehow? Keeping in mind I can't even get a signal, and apparently have no sms credit (not sure why) to try and get it enabled.
Wondering whether it would be possible for a kind person still in Vietnam to help me add credit to my number and/or set up roaming?
Might seem a bit frivolous but I'm on a tight budget and had quite a bit of data yet to use and topped up especially for use in the rest of SE Asia.
Thanks in advance!
