AIS Sim2Fly: Asia Data Roaming for 20 Countries Preloaded Data SIM Card 4GB / 8 Days Japan, Korea, Singapore, Malaysia, Hong Kong, Laos, India, Taiwan, Philippines, Cambodia, China, Nepal, Australia

Worked perfect with my Att unlocked Samsung Galaxy Note 8. Literally turn off phone when you land, insert sim card, give it a couple of minutes and all is good. I went to Seoul, Korea from San Francisco, then Korea to Taiwan within 10 days and transition was easy, didn't need to do a thing. Will definitely buy again, as this is MUCH cheaper than when you got to Seoul especially. In Taipei they had some unlimited SIM cards for 10 dollars 5 days. So it really depends on your trip. If multiple countries within a week or so, this will be good at 18$

Did not work at all in Japan. After inserting the SIM in the phone received several text messages from AIS-some in Thai and some in English. The English one said the service was activated. However, there was no internet. Verified the APN was `internet', tried forcing 3G as well as 4G but no go. The phone (US Moto E4) supposedly supports the bands used by softbank.

It only worked the first day and after that, I had to buy another one and use another SIM card. Not good for Japan or any other places.

Worked in Vietnam, Hong Kong, and Laos, Thailand and Macau perfectly for 7 days I was there. To activate...Inserted sim while I landed at hong Kong and instant 4g. Same when I landed for Laos and Hanoi. Phone is a Motorola g7 power international so phone has all international bands. I use phone in USA as at and t and works flawlessly. Vietnam had 4g everywhere in Hanoi and on our way to halong bay on vittel network. In Laos (vietianan) there is 4g everywhere with lao gsm. In Thailand it was AIS ...go figure Seller answered all my questions very quickly about the countries sim worked in and made sure expiration date was good (March of 2020 I believe) I would buy again in a heart beat.

These are fantastic. My wife and I visited Japan for 7 days and after online research, I was ready to put down $75 for a wifi router and carry that around (and return it at the airport as we left). However, these prepaid SIM cards proved to be perfect and more. With a wifi router, I would have to wait in line to rent one at the airport and then need to carry it around, charge it often, and then return it before I left. With this, I inserted the SIM card to my iPhone 6 plus (saving my Verizon SIM card to put back later) as I landed at the airport. I turned my phone off and then on. The SIM card did the rest and got me connected to the best cellular plan in Japan. 4GB was plenty for me in the 7 days that I traveled all over Japan, using my Google Map everywhere. And then at the airport, I simply removed the AIS SIM card and replaced it with my Verizon SIM card. And that's it. Side note: AIS will send you several texts (both in English and Thai) about adding days to your plan. Disregard it. The SIM card can't do any of that. It's set to be active for 8 days and then to be thrown away.

My fault for not reading the details carefully, but the sim only gives you data, no calls/messages

This was a piece of crap, it didn't work when I traveled to Japan and China. I can not do rate and recommend such a bad stuff.

Easy to use, plenty of data for moderately heavy usage. Fast speeds, just like the carriers in the US. The company that makes these is apparently based in Thailand, so you will get a Thai phone number with this SIM card. I didn't use this for regular phone calls though. there are so many other apps (like Hangouts and Google Voice) these days that you can call people on that it almost doesn't matter what country these come from. Very satisfied with the price and value of what you get. It is also priceless to land in a foreign country and your phone works immediately, without having to search for a place to buy a SIM card.

Used it for our trip to India and Nepal. Worked great, just popped it into the phone and it worked as soon as we turned on the phone after we landed in Delhi. The item listing and package we bought said it was 4GB/8 Days but the confirmation text message we got when it was activated said it was 6GB/10 Days.

Thanks

La carte n’a pas fonctionné pour moi, on parlais de facile d’utilisation. Juste à installer dans mon téléphone et que ça allais marcher. A l’arrivée je tente de l’installer dans mon téléphone sans aucun résultat. Je tente de l’installer dans le téléphone de ma copine aucun résultats. On a finalement acheter un carte directement au pay et ça marche sans problème.

During a recent one-week trip to Tokyo (mostly the Ikebukuro area), the Sim2Fly card worked without issues. The phone had a Rogers SIM and activation of the SIM2Fly card as a secondary SIM in Japan allowed an easy switchover.

It works but I can’t understand the instructions. No English
