UQ mobileのSMS/MMS

先月、母のスマホをAquos Sense2@UQmobileに買い替えたのだが、ぬぬぬメールはどうも住所録との連携がわるいらしく、誤配信されてしまうらしい。
Googleのメッセージアプリに切り替えてもらったところ、とりあえずうまく行っているみたい。

それはともかく、UQmobileの店員が、上記の状態で解決のために端末の買い替えを勧めてくるとかよくわからんことを言っていたみたい。
言いたいこと色々ある。

YI 360 VR

YI360 VRが送料など込で180USDなので、買ってしまった。
今持ってるinsta360 airに比べて、総画素数で4倍ぐらいになるので、だいぶ綺麗にとれるはず。
