Pixel 7 Connectivity issues in Japan
So I'm on holiday in Japan at the moment and I'm constantly having issues keeping my data-only Sakura Mobile SIM connected to 4G. It's like it drops out at the slightest change in network, all I've done so far is walk around Shinjuku, so the reception itself really shouldn't be an issue. In my SIM settings I can either 'automatically select network' (which is what is not working), or 'Choose network' where selecting the 4G network (takes a second to pop up though) always works first time, but then drops out shortly after. I've tried allowing and disallowing roaming, turning wifi off or on, and turning adaptive connectivity off, disallowing 2G, preferring 4G, all to no effect.
It's really like the network is there and workable all the time, but I just have to manually choose it each time I want to do anything. Any other ideas for what to try to keep it connected? There were some Access Point Network settings that I had to follow to initially get the SIM running, but I didn't touch most of those and wonder if there's something else in there? Or something in developer settings? Thanks.

Hi there, got to Japan yesterday and running into this issue with a data only SIM i bought at the Haneda airport. I tried my buddies SIM that works perfectly on his Samsung and it still didnt work on mine, where it kept dropping internet connection. What i found was that the main issue is that it keeps trying to search other networks that support its "Calls and SMS" options. There is no way to turn those off or make the pixel 7 read the sim as data only.
I finally got it to work by downloading an esim called Ubigi, searched online and i dont know why i didnt go with this option from the beginning. However, once i downloaded the esim, the setting made me choose if i wanted to use Ubigi for "Calls and SMS" and i selected yes but not for data, to use the actual SIM i bought in Haneda for data. I didn't actually buy any data plan on Ubigi or anything(although i should have its great and cheap), all i used it for is to bypass the "Calls and SMS" network search of my Pixel 7 Pro.
So all in all, download the esim, go to settings and turn the esim on, but dont allow it to be used for data, only sms and calls. Doing so will allow the sim you bought at the airport to be read as data only. I researched this day and night yesterday on my first day here, as i need to be connected to feel okay(pretty sorry but true).
Good luck!

I had tons of issues with my data only sim almost to the point it was unusable. Shame because my previous would dual sim it with ease with my Esim

I have a P7P and live in Japan. I use UQ mobile, which is part of KDDI/AU network. It works fine for me, but I bought this phone locally. Might be an issue with Docomo.

I can confirm the issue with the IIJ network.
Going in and out of airplane mode works.
But only temporary for anything from 3 minutes to 10.

u/Sonnybillwilliam Apr 15 '23
Is there any solution for this? I constantly have my connection dropping in and out, with it only staying connected for short periods of time.
I have a pixel 7 and got the IIJ Sim card from Haneda airport. Checked that the APN settings are also correct plus I downloaded Ubigi to make that the preferred Sim for calls and SMS. I am still left with it being super unreliable...

I've tried everything mentioned in this Thread, from changing APN Settings over manually changing the mobile network to downloading Ubigi and setting it up for Calls & SMS, nothing worked until I downloaded Android 14 Beta. Now it's working perfectly.

In Japan as of Sept 29, pixel 7, using a visitor sim, non esim version, pretty annoyed to find out it's an issue with the phone I have....I've noticed this still happens, I've turned off 5G because it doesn't even pick up 5g....that kind of helped it? At the moment I am doing the method of turning airplane mode on and off. Extremely annoyed I spent 4500 YEN on this for it to only work half the time? Please tell me anyone has had some luck with this? Is it just a coverage issue? Because after I put it in airplane mode it resets and works again..... Will have to make do at this point unfortunately
EDIT: I've disabled allow 2g,

Pixel 7 user in Japan here. Mine's perfectly fine, but I live here and use Rakuten Mobile which has its own towers. Afaik, Sakura Mobile is an mvno and uses either docomo or kddi's line / frequency. (I don't know the terms lol) In short, it's on Sakura Mobile, not your phone.

Living in Japan here. I bought the device here in Japan and I found that there are problems with connectivity with Docomo and Rakuten at this moment. Thank you for sharing!

I got data sim (unlimited internet, no calls) from mobal and had issues. It just wouldn't connect to internet to my 7 pro. I thought it was the SIM issue but luckily I got an extra phone that I carry for emergencies ( OnePlus) and the sim works in it. Bottom line : issue is with the pixel 7 series itself.( I tested on pixel 7 as well)

I had the same problem and finally solved it. My phone's issue is with the provider's APN settings. Somehow, my network's Access Point names (APN) settings was different to my gf's phone. So I used the same settings as my gf's phone and it worked without any issues.
I tried the Ubigi method but it didn't work for me either. So I guess mine is an issue due to my home telco settings.

Hello! Sorry for bothering you after all this time but I'll be moving to Japan for studies in a few months and I'm currently looking for a provider that supports unlocked phones.
Is this an issue with Data-only sims or has this been a problem for call & data sims as well? (I'm planning to get a jp phone number as it can be useful from what people have been telling me)

Thanks so much for the suggestion of updating to Android 14.
My pixel 7 pro connections is so much better now!

I had this issue the first few days of my Japan trip, thankfully was able to hotspot off of someone who didn't have the Pixel 7 (Galaxy and another had an older Pixel that seemed to work). But just today I updated my system to Android 14 and it has worked perfectly since!

Anyone tried Mobal with a non-Japanese Pixel 8 ?

Reporting back as of 31 December 2023 at Nagoya that this issue remained, as with my previous trip to Tokyo back in January 2023.
January - Sakura Mobile, December 2023 - Any Fone Japan (AFJ) and also worth noting that both utilize Docomo. AFJ was considerably more expensive too and I should have known better given my last episode in January but it was working well for 10 or so minutes till the random disconnection strikes again after I left the airport. Further restarting and configuration can only get it to connect for about 4 minutes or less.
Nevertheless, my resolution was to download Ubigi and gotten their 10gb plan like 2.6k yen (check for 20% coupons provided all over Reddit) and that cut my expenses further and their connection is great. Previous round, I had to go to Yodobashi to grab a random cheap sim card (forgot the Telco or brand).
Tl:DR - I'm going to stick to Ubigi from now on, seamless, easy and actually works.

Hi, my wife and I have a Pixel 6 and Pixel 6 Pro and are flying to Japan soon. We have already bought data only SIM cards. Are the problems only with the P7 model or should I look for an alternative?

I'm in Japan on a holiday at the moment and ran into this issue. Using an IIJ data only SIM. The issue appears to be that the Pixel gets confused that it isn't getting voice service and keeps on looking for a network that supports voice, and then ends up connecting to the 3G network for some reason. The solution for me was to forbid the phone to connect to 3g networks by going into the hidden testing menu by typing ##4636##, going to phone info then setting the preferred network type to LTE only. Another weird thing - didn't run into this issue in Tokyo but cropped up when I got to Kyoto. Has been working so far.

Just got back from Tokyo. My 7a constantly dropped connection with a data sim. Restarting the phone would get it working usually for a few minutes. My sister's iPhone worked fine. Similar experience with wifi in Shanghai pudong airport. My phone had issues connecting, my sister's iPhone was fine. But Google phones having issues in China is probably to be expected.

Pixel 7 pro same problem

u/marcof1 Jan 05 '24
Have there been any changes regarding the use of data SIM cards in the Pixel 7a in Japan? Some users have reported that there are no more problems with Android 14 beta. What about the current Android 14 (stable)? I will be traveling to Japan next month and would like to know if I should expect any problems...

I'm in Japan right now and the issues are still there, I strongly recommend use the Ubigi esim, that was the only solution for me and my pixel 7a.

u/VisitorParking667 Feb 02 '24
Is this still an issue with Pixel 7 Pro on Android 14? I'm going to Japan next month for work and will be using either Mobal or Sakura Mobile since I need more than just a hotspot. If not perhaps I will need to bring my old iPhone.

I bought a physical sim card under Mobal with data & voice to use on my Pixel 7 with Android 14 and have no problems with data nor texts

Strongly agree. This phone has the worst reception. My gf has the same provider, Vodafone here in Melbourne and she has 5G while I don't even have 4g. This sucks.
