@darius They are great, but be aware of silly restrictions. For example, Samsung Galaxy devices allow either 1 SIM and 1 eSIM, or 2 SIMs, or 1 eSIM - you can't have two active eSIMs!

Problem I have now is that my watch often rings and my phone (on same eSIM, shared number), doesn't...and if I answer on watch it overheats about 5 mins into a call!
