Yes it is, just that someone is not aware of it
I find it very useful, especially when you travel to a more expensive country
Also, it doesn't affect your physical sim, you can just simply apply a transparent film and run the setting switch when you're locally there too
When you're back, all you need to do is to switch back locally
For e.g) a single european country, you can use any of their 3 vendor, switzerland per say
Orange / Swisscom / TDC Sunrise
