lol, not a very active thread indeed
Can't really help you with the district 1 info, but concerning the 4g, it seems it has not yet arrived here :

And as far as an internet plan using a pocket wifi (if that was your question...), I would go to one of the stores instead of purchasing a package via text, as it seems as I got more data when I went to the Viettel store directly for my 100 000d then when I got the package online (from what I read, you can get 20GB for 100k at the store, but only 1.5GB for 120k by text... All of this was lost in translation, but had my packages last all month from the store (as a back up), while expiring after a few days from text purchase...).
