I used this in Albania and the signal was mostly stable. Very affordable and good to go. I am not sure of other countries.

It's more convenient than buying a new SIM card. If you don't know how to use it, try checking out TikTok. The internet might be a bit slow during calls, but replying to messages is normal.
