Not needed for IPTV on Mobdro or showbox. Between those two you get all the tv you could ever want. Also not needed for banking, email or other apps like facebook or MHF etc. Been abroad for 3 years and never needed one. Not found a use where I would either.......yet! ( using Portuguese mifi)
We use Hotspot Shield which costs about £22 a year, it works to get access to catch up TV while here in Spain, we can use Mobdro and other sites but they don't have subtitles which we need.
Rant on: ITV disgracefully still do not have subtitles on their catch up service : Rant off
I have just changed my internet security to Bitdefender (it's a paid for programme which has excellent reports) and discovered that it's supposed to have a VPN option. I've never bothered with VPN's before but I'll probably install it on the laptop before going away in January and give it a try.
I have tried several VPN's over the years, but for the last half year, I stuck with NordPVN. Easy to use, works with Netflix US and is fairly cheap if you compare it with the likes with ExpressVPN. I had a few minor problems but the live customer was very helpful. Would recommend! I saw an ad also that they have a great black Friday deal right now, I believe the coupon code is "blackoffer".
Just a quick nerdy note about VPNs. They work by encrypting your internet traffic and tunnelling it through to an endpoint where it gets decrypted and pops out into the wider 'net.
The tunnelling effect that makes it look like your device look like it's somewhere else is why VPNs are used for faking your origin to get around region locks for streaming media.
The primary reason I use them is the encryption bit. If I'm using a dodgy coffeeshop or campsite WiFi, there's no guarantee that your traffic is actually private. By using a VPN, it massively reduces the chances that you can be snooped or spoofed.
There's then a third reason for using VPNs, because you are trying to remain anonymous, but VPN alone isn't a complete solution for that.
