You can search for "Saigon International friend" group on Facebook. They have weekly or monthly meeting where many nice girls (office girls, students) show up. They all speak english. I ve never been there but see their notice, photos updates frequently. sounds a good activity here in Saigon. Good luck!
If it's to prevent the remote detonation of bombs (which it wouldn't, there are plenty of other methods that could be employed) then surely it would be more logical to prevent incoming calls and allow outgoing. . . or, just prevent any calls/SMS at all.
Hi britmaveric, Being objective you can just check on internet and surf each company website. You can take the list of TripAdvisor as reference to see the companies available (not for trusting the rating since nowadays is populated by fake reviews). Being subjective: As representative of Bhaya you can check our websites (bhaya, the au co and legend halong) and see what best fits your needs. I believe our price / value is very competitive. Carlos
They claim it is for national security purposes, which could be to help prevent remote-controlled bombs or catch people sending LM messages over the Internet. But I think it is just increasing control over the population in general.
