you can get routers which take a SIM card and there are some routers you can add a VPN to. You can try the phone as a hotspot method but not sure why you'd then need to run through a router. You could just put the VPN software on your phone and use the phone itself as a your wireless router

You can get 12 months dtac SIM with unlimited data at 30mbps (fast enough for 4k streaming) for about 1300 baht. You can pick up a 4g router for about 1000baht

If you want direct them Eva. If you prefer the journey broken a bit then Oman are very good and you can get lounge access with showers for not much money. If you've got the time maybe even do a day in Muscat on an extended layover if you can

As Garrett says, valid from day of issue. However, remember the visa can expire and you can remain in the country past that time. If you enter on the final day of the visa's life you will still get stamped in for 60 days and can extend that my another 30. The fact the visa has expired at that point means nothing, unless you wish to re-enter the country again

Turn up, show your passport, they'll stamp you for 30 days and let you on your way

Credit cards/apple pay/Google pay can be used in most major shops, full service restaurants, family mart/7-11 and Lotus's. It's the smaller places and street stalls and independent places you'll want Prompt Pay and Union Pay for (plus Makro and Supercheap)

When you enter on an O-A they will only stamp you in for as long as your health insurance is valid for (up to 1 year from entry). Most are one year policies I believe. If you know it will only be a few months before you'll be covered by your wife's insurance then you could go with Tune insurance which does monthly, however I think thats closer to $100 a month and you'll also have the expense of departing a d re-entering with the new policy so may not work out at any cost saving. If you're going to be covered from your wife's then just go for that hefty excess policy and think of it more as a fee for not having to tie up 0 baht for 2 years

@Bill ********

shouldn't be too much higher then. Check out misterprakan.com brokers for your O-A insurance options. Somebody mentioned the other day that you may be able to use a policy for from your home country that would be suitable but the ones on the above site are guaranteed to be acceptable

What kind of age are you Bill? If early 50s you can get one years health insurance for the o-a visa for about $500 (with quite a hefty excess if you actually want to use it) but the older your are the heftier the premium is

If you're still resident in UK then even with Polish passport you can apply for an e-visa. If you're back in Poland then it will be the old fashioned way
