I'm pretty sure these questions have been asked here plenty of times but I wasn't sure where else to ask and I am leaving for Bangkok next month so any help will be greatly appreciated. Like I mentioned on the introduction page this will be my 7th time to Thailand. The first 5 were simple due to me going to a muaythai camp but the last time I had some issues.
First was the wifi. I rented a cheap apartment but the wifi was pretty bad and I work online so I'm wondering what options there are. I've heard about sim cards and pocket wifi's. Not sure how fast and reliable these are. If there are any better options please let me know. I'm talking fast enough wifi that's reliable and can last me the 85 days I am out there.
Secondly was visas. A few times I've gone out for only a month but 1 time I got a 90 day visa from the help of a camp that sent me an invitation letter. Last time I went out I couldn't get this at the Thai Embassy in London so I got a 60 day visa instead and got a 30 day extension whilst I was out there. Can you still do this? I looked at the requirements and they seemed to add on a few things like proof of sufficient fiance and some type of booking reservations. I didn't need these things last time.
And lastly any recommended things to do in Bangkok whilst I am out there. The mistake I've made in the past was concentrating too much on muaythai training so when I wasn't training I would be eating, sleeping, working or watching fights which was fun but I did very little exploring. Oh yeah I almost forgot when does the rainy season end? I'll be arriving late september.
