Using a refurbed American AT&T S7 edge in the UK

[AC Question]

Hi everyone,

I have just bought a refurbished S7 edge from eBay and it turns out it is an American AT&T handset. It is unlocked and works with my GiffGaff Sim card but I have a few questions I'm hoping y'all could help me with (joke - I'm not American!)
The phone is full of AT&T bloatware and other stuff, can I get rid of it so that I have a clean, unaffiliated phone? I would rather not root it if possible as I'm not really that tech savvy.
Certain features, such as WiFi calling, don't work as they require a live AT&T account, which I don't have. Can I bypass this?
The other thing I'm worried about is whether or not I'll be able to receive any OTA updates? It feels a bit like I'm in limbo with this phone!

Thanks.

Don't worry about rooting, it's not possible on this phone. Wi-Fi calling won't work but can't be uninstalled like any other bloatware as the device can't be rooted and no, you won't get updates. You need a valid AT&T sim for that.
