I use it for some groups around investing, but truely not a fan. It's really hard to discuss things, it's more of a chat. Facebook in social group like this I think is superior. We can create different posts and then discuss them in a more organized way.
To correct it you must go back to port of entry (the airport you arrived at) they can't fix at any other port or immigration office.
If your tourist visa isn't used, then you could exit and reenter on it to extend your total time.but if it's used, you would need to go have it fixed or exit before your current stamp.
You looking for a router that can directly connect to a VPN service.
You still need to provide a VPN service with the desired ip address. I recommend using a service that you can get a dedicated IP address, you will have less issues. Private internet access would be my personal choice.
Gi. net and it's copies are pretty much the only ones that would be travel size, and the really small one doesn't support this feature. It's not an extremely common feature.
You can also use any router that can support open wrt (replacement firmware) as open wrt can support this. If you are more handy you could use raspberry pi for this also.
This will get you going finding a router and setup that will work for you:
You don't need an appointment for resident certificate, it's fast. After you have your 90 day report (photo copy) go to the document check for resident certificate station next to the where you get a queue. They check your documents and then give you a queue number.
The longest I have had to wait for my number to he called was probably 10 minutes, but it's usually less. Can usually be in and out for a resident certificate in under 30 minutes, which is usually mostly the walking to and from the parking.
They mail you resident certificate, it generally is around 2 weeks.
You probably can't do it at all. I don't have SCB, but krungthai and Bangkok Bank. When I got a new phone, I could not do it alone as a foreigner. Had to go into branch to and have the staff verify me manually to login new phone.
