What companies in Phuket provide the best broadband services, looking for 500mps or greater with stable service. 

All of them, e.g. 3BB, TOT, True, etc.  Each customer has his/her preferences and their reason on being loyal customers.  I am happy with 3BB, very good customer service.

Thanks for the info.

Yes. We also use 3bb. But the answer is more what location you are in. 3bb is best many places.. AIS might be better somewhere else based on their lines.. True or even 5ghz over the phone might be best for some people also... 

I am in contact with an office manager who's in charge of renting out Condo's. I am trying to rent a condo that has good internet. I know in Thailand it's not going to be good 100% of the time. The last Condo I stayed in Phuket the internet would stop working a few times a week, but this was a few years ago now so hopefully its improved. The office manager has said the internet service is from TOT and 3BB, are they in a partnership or is this incorrect info.

I live in a Condo that has a common internet connection for each apartment.  The connection was atrocious.  I decided to have my own internet connection with 3BB.  TOT and 3BB are separate ISPs.  It all depends on where the ISPs have their connection points to your Condo.

The link is to an article dated 22 Jan 2021.  Maybe it has grown exponentially since then.
