All gave excellent speeds. In Myanmar buy more data then you think you need because the wifi is horrifically slow and the 4G is superb, so you’ll be using it by default.

Picked up all at airport kiosks at decent prices. Tru in thailand was more expensive as an actual ‘tourist sim’ but unlimited data.

Previous experience with Smart was lots of dead spots with no signal, especially inside buildings. No 4G, speed was very slow like too many people trying to use and it took minutes to refresh Facebook feed or just time out.

Perfect – that is what I had read but wanted to check!

Thank you 🙂

Yep, there’s no problem picking up micro or nano SIMs across Asia, since pretty much every phone sold there uses one of those two types. You’ll often get a card with cut-outs for each size, or the vendor will ask which type you need. Failing that, on the rare occasion you can’t get a (typically) nano SIM, the vendor will cut it down to size for you, usually for free.

Really helpful post, just had a few questions.

Are you able to purchase Nano or Mirco simcards in these countries?

I will be travelling across Asia for 8 months and the two phones I will be taking with me require either a mirco or a nano sim? (Nano is the one even smaller than Micro)

Thanks!

For a trip of that length, I’ve found no travel/international SIMs offering what I would call reasonable rates, unless you plan to barely use your phone at all.

Unless you’re from the US and are a customer of T-Mobile or Google’s Project Fi, roaming with your existing carrier is likely to be totally unaffordable.

If you’re in each country for 3 weeks, buying a local SIM makes by far the most sense. You don’t say which countries you’re visiting other than India, but in SE Asia, at least, it’d be rare to be able to walk from your guesthouse to dinner without passing a vendor that could set you up with a SIM for around $10-$15 with enough data, calls and texts to last the duration of your stay. Things are a bit trickier in India (we’ll be posting an article about that soon), but still possible.

I’ve never found the process annoying, costly or inconvenient in any of the countries listed in this article.

I’m going to be travelling through 7 different Asian countries, I’ll be in most for 3 weeks and then the last, India, for 7 weeks.
I’ve been trying to find a travel sim that has a good price for calls, txts and data within country and to the UK and i’m having no luck at all!
I’ve found Travelsim and Gosim and those kind of ones too expensive and then the idea of having to buy a sim card in each country is just annoying/costly/not convenient.
Are you able to shed any advice for my situation please?

Just follow the link at the bottom of the post (this one) to see all of our SIM coverage. At time of writing, we’ve got a piece on Taiwan, but not the other places you list (although we do have an article on renting a Mifi device in Japan as an alternative option).
