Mobal Opiniões 

Second time using Mobal sim. Was a little nervous last year when we first used their service but it worked seamlessly. Very happy and again this year using the same service. Highly recommend and happy that they donate profits to charity. Can’t go wrong.

I recently changed to a new phone and discovered that Mobal eSIM cannot be transferred to a new device. I had to request a reissue of the eSIM, and this resulted in my Japanese phone number being changed.

This caused serious problems because many Japanese apps require SMS verification linked to the original phone number.

In addition, Mobal charged a reissue fee of 3,300 yen plus another 831 yen, just to change the eSIM, which is quite expensive considering the number may also change.

Because of this, I lost access to several services and had to spend significant time recovering my accounts and many seem that not possible to access anymore. I hope Mobal improves this process or at least clearly warns customers about the risks of using your esim!

Update after Mobal response:

Thank you for your reply. However, the suggestion to contact websites or services to update contact information does not work in practice.
Most people who use Mobal are foreigners who do not have a Japanese residence card or Japanese ID. This is exactly why many choose services like Mobal in the first place.
When my phone number changed unexpectedly because the eSIM could not be transferred to a new device, many Japanese services linked to my account stopped working because they require SMS verification tied to the original phone number.
For example, Mercari replied by email that they cannot provide support regarding account by email. Instead, they directed me to their Help Center and told me to contact them through the website. But that process leads back to account verification requirements, and when access is lost due to a changed phone number, services like Mercari require Japanese ID such as a residence card or Japanese driver’s license.
If users already had those documents, many of us would simply use normal Japanese mobile carriers instead of paying higher prices for services like Mobal.
So telling customers to “contact the websites” is unfortunately not a realistic solution. Changing the phone number due to an eSIM reissue can cause serious and sometimes permanent loss of access to many services.

I used Mobal during my two-week stay in Japan. Everything worked flawlessly, everywhere I stayed, including Hakuba, Nagano, Matsumoto, and even Jigokudani Monkey Park! Mobal also worked great in the Tokyo subway system, where it was essential. I was also able to connect to apps like Uber very quickly. I will definitely use Mobal on my next trip to Japan!

A good service, I used it for 3 months. However they charge a lot for an eSIM & once you are done it lapses unless you keep paying for it, it then finally lapses for good unless you fully reactivate.

It is for the above reasons I have gone with another provider for my current trip to Japan.

It is unfortunate that Mobal make the grab for cash. The service could be so much better, if they were not so greedy.

It was really easy to have phone and wifi. Already one year now. I LOVE Mobal and their mission. I Will stay here for ever. Really foreigners friendly.

I had used 5G unlimited data eSIM during my 2 weeks stay in Japan and the connection was always great even on the tops of Japanese Alps where I was testing japow🏂🏂🏂 and Mobal in the same time

Mobal was the best eSim for our Japan trip. Unlike most tourist eSIMs, they give you a real Japanese phone number — essential for restaurant reservations that only accept local numbers.
The coverage? Flawless. They use Docomo, Japan's largest network. We had perfect signal everywhere, even in remote mountain areas.
And when I messed up the installation (totally my fault), their support fixed it. No drama, just quick and friendly help.
Highly recommended.

I had the pleasure of using the unlimited 5G eSIM for two weeks during my trip to Japan, and let’s just say it has made my experience here infinitely better. I’ve been able to use it while taking the Tokyo trains, allowing me to stay connected even underground which is super important for navigating this huge city! I would recommend this over a limited monthly renewal plan, as those can sometimes be a hassle when you go over your data amount. Overall, 10/10 experience and I will be using again for my next trip to Japan!

The data is very fast and smooth

I would give this company a ‘0’ star. The experience was awful. Firstly, it took me a significant amount of time to set up the mobile settings to receive calls and SMS, which I did not face with other providers. Additionally, they suddenly closed your account even though you have paid all the required money. No apology, no remedy plan, no customer service. They just took the money and wished you good luck. So if you want to avoid hassle, do not use it.

Karta eSIM z japońskim numerem telefonu wiele razy mnie uratowała. Mogłam dzwonić do hoteli, robić rezerwacje w restauracjach lub wyjaśnić problemy z nadaniem bagażu. Bez numeru telefonu nie dałabym rady!

Internet też działał świetnie na terenie całej Japonii. Nie zacinał się i nie było z nim żadnych problemów.

Od momentu odebrania instrukcji na lotnisku do wylotu z Japonii wszystko było proste w obsłudze i zupełnie nie musiałam martwić się o internet!

Mobal wiele razy uratował naszą podróż po Japonii. Chcieliśmy tyle zobaczyć a czasu było mało:) Dzięki temu, ze mieliśmy kartę eSIM z numerem telefonu, mogliśmy zawsze przełożyć nasze rezerwacje i dopytać o szczegóły właścicieli atrakcji. Japoński numer dawał nam sporą przewagę i czuliśmy, że dużo łatwiej jest nam załatwić dowolną sprawę. Wszystko działało sprawnie i bez żadnych problemów. Dzięki Mobal!

I ordered a physical SIM from Mobal for my trip to Japan, because my phone Samsung A53 doesn't support eSIM. Wanted to have it shipped (to Netherlands) so i can have it before landing in Japan. I got it shipped in about a week, and i even entered the APN provided setting in advance in my phone. A few seconds after inserting the SIM at Narita airport, i had instant connectivity, which was so surprising and comforting! I had fast and reliable signal throughout the 2 weeks i traveled, which made my trip easier and even more memorable. Would choose Mobal again for traveling to Japan!

I've been with Mobal for more than 3 years now, and it's been a breeze. Data, SMS, voice -- zero complaints about any of their services. Mobal is how a professional telecoms company should be!

I went on exchange abroad to Japan by myself. It was my first time in Asia, and as you can imagine, I was really concerned about being able to use my phone since I didn’t speak any Japanese at that point. Getting a SIM card seemed like a big challenge. However, Mobal took all those worries away. It was a very simple and stress-free process. I bought my SIM card on their website, got an eSIM with data, and chose an activation date for the day I landed in Japan. From the very first minute in the country, I already had access to the internet.
Next, I wanted to get a phone number, so I ordered a second eSIM with data and phone calls. The process was very simple, I chose my plan, paid, and selected a pick-up location. The location I chose was at a station, easy to find, I just went there, picked it up, and it was ready to use right away.
I have been using their SIM cards for two months now and have never had any problems with signal or slow data. I told my other exchange friends about it, and they’ve had the same experience.

Sneller dan verwacht aangekomen wel extra moeten betalen aan Taxen maar dat dacht ik al .

Great 4G LTE connectivity throughout my 14-day (9/22 to 10/05/25) trip in Japan. KYOTO, NARA, OSAKA, TOKYO. I do wish 5G data speed was available. I do love the massive data plan 50GB for 16 days.
I did have a little hiccup activating my eSIMs on the 1st day. I was getting worried that I had wasted my money. One eSIM had the wrong preset APN settings. I needed to find a local SIM retailer in the HND Airport for help and manually change the APN settings.
I did not get the activation email of the 2nd eSIM until 12+ hours of arriving Japan. I requested the activating email before I departed USA on 9/20/25 @ 1600 ET. The activation email information didn't arrive in my inbox until 9/22/25 @ 1800 JST. I had to email Mobal service center for the activation email when I arrived in Japan using the airport's Wi-Fi.

All went smoothly except:
* the set-up is entirely self-service. The instructions are clear, but some human assistance at the collection point would be even better
* my first attempted connection was in a rural area with a very weak docomo signal and was unable to connect. No problem after moving to a town. A warning from Mobal would have helped.
I would use Mobal again.

I've used Mobal before and was not disappointed so it was natural to use the service again. This time it was even easier to set up on my phone, not because I've used it before but because Mobal have improved things, it is almost a single click process, nothing to make a note of, nothing that's difficult to understand, just a QR code to view and that's it.
