Hi everyone
In case you need smartphones, either for yourself or for your loved ones, without breaking the bank, I recommend you take a look to the Moto g64y (note the 'y').
They can do osaifu, they can read mynumber cards, and they have esim modules for when you travel abroad, so they check all my boxes. They can also be found almost new for only 15k JPY, so you can equip a family of 5 for the price of an iphone SE (the cheapest iphone, dates from 2022).
Those 'y' are Yahoo-specific 4G RAM versions of the popular Moto g64 (no 'y'). The regular version has 8G RAM and cost 24k+ new. The Yahoo-specific version ('y') has 4G RAM instead, this is the only difference afaik, and sells for much less. They are not made for heavy games or multitasking but do well with all everyday tasks of anyone not a power user imho. There are Yahoo apps installed by default but you can remove or hide them easily.
I gave the same tip for the previous model (the g53y) one year ago, and this is simply a model update. I can confirm the g53y work really well, and are great bangs for the buck.
I hope this helps some people save some money
Cheers
edit : as pointed out by u/tsian , those phones work with any carrier, as all phones have been SIM-free by default for a while. I have used the g53y with Biglobe and Povo successfully. By the way I recommend Povo for cheap access (for kids for example), it is 1000y for 3G for a month, you can change data plan easily on the fly, and you can also not pay anything during half a year and still keep the phone# alive until then.
