I bought SIMBA card $25 last week plus top-up $15, before I went overseas.
It has been active at least 48 hours, confirmed by checking the status via SMS "simba" to 1218 that my card is roaming ready, got message "Congratulations! Your SIM is ready for roaming. Please visit
www.simba.sg/roaming
for full roaming details."
Arrived in Turkey, NO SIGNAL at all. Turkey is part of Group C, which I read somewhere that it is not free roaming, and that it cost $15/GB. That's why I top-up $15 before I left SG. No luck.
Arrived in Bulgaria, NO SIGNAL at all. Bulgaria is part of Group A, which is supposed to be free roaming (part of the $25 package). No luck.
I already checked the APN was TPG. Already roaming enabled. Already turn on/off plane mode. Already restarted the phone. No luck.
It felt like a scam.
Even my Singtel hiCard at least got registered to the local network for both countries, even though I couldn't use it for internet because I didn't buy any roaming package for it (prepaid hiCard doesn't have roaming package to Europe, postpaid has).
