This is highly relevant to my interests.
So, can someone give a qualified answer, - is some provider provides coverage all over Europe? Ideally, +UK.
I could never find one. Unlocked Huawei or ZTE turn out a pain in the ass to set up with every country provider. Two summers ago I ended up with a handful of dongles in my backpack, no kidding. Then like, okay Vodafone has its own standard so I got their dongle and buy Vodafone sim with local tariff in every country. But this is also a huge mess with all these sims, and also costly.
So, what can be done in this case?
