Yes, It was continued yesterday. But some branches are out of 4G sim so they might tell you it's not available

I don't know if they start selling. But they had stopped when i asked them 2 weeks ago. This week i had upgtaded my sin to 4G

u could also upgrade ur 3g to 4g

No it's not. I tried to get one yesterday and they said they have stopped selling 4g but the tailer said to comeback next week and check for it.

Still available. I got one last week.
