Brandon is completely correct. You clearly don't know the difference between a tourist visa and visa exempt entry. Shameful you are commenting to correct someone when you don't know basic immigration terminology for Thailand.
There are only 3 mobile carriers, and 2 of them have merged (True /dtac) although they still operate separately. All are quite similar, and you'll be shocked how cheap data is in Thailand.
You've completely misunderstood the visa. The DTV is valid for 5 years, and during those 5 years, each entry allows you to stay for 180 days. You can also extend each stay one time for another 180 days before you must leave to get stamped back in for a new 180 day period. In other words, you can enter Thailand on that visa, stay for 1 day or 180 days or anything in between, leave, and come back anytime within the 5 year validity period and get stamped in again for a new 180 day period. It doesn't matter if you come back the next day or don't come back until 4 years later. If you actually need to stay more than 180 days during one visit to Thailand, then you can get the extension that allows an additional 180 days. After 360 days, you would need to exit, then re-enter, to activate a new 180 day stay period. Note all this is assuming no changes by Immigration to entry rules for that visa during the 5 year period.
It sounds like you got a multiple entry re-entry permit from immigration at some point during your stay in Thailand. This permit allows you to come back and resume a stay valid until your original visa's allowed stay through date of 7 November. Essentially, it allows you to leave and come back as if you never left, and you still retain the original date of 7 November that you were allowed to stay till.
If instead, you didn't mean that you have a re-entry permit that you paid for within Thailand at immigration, then you might be referring to a multiple entry visa that you got from a Thai consulate outside Thailand before travel. If that multiple entry visa expires 7 November, it means you can come back any time up until that date, and still get stamped in for the full allowed stay period (for example, 60 days for multi entry tourist visas, or 90 days for multi entry Non-B visas).
Ah OK, didn't see your other post. Yes, number changes are ridiculously annoying. I had to do the same myself once with Bangkok Bank. They have to send the change to headquarters, and it also took me 3 tries before the change went through.
sorry, just trying to help. How can a banking app be broken. The app is loading fine for me so it's not having any availability issues. Perhaps your phone is having an issue? Did you try updating the app, or uninstalling and reinstalling it?
In addition to Promptpay, when you open the Bangkok Bank app, you can click "Transfers" then "Other Accounts" (the first option, above the Promptpay option), then select the recipient's bank and enter their account number.
