Here in Australia the cost for a roaming plan is $80/month (£38.50/m. It’s like having a wifi with you all the time that you can connect your phones, tablets, laptops to anywhere. The roaming plan gets you 50GB, can use anywhere in Australia and up to 12 nautical miles offshore, up to 100 mph (attached to your car either on the roof or under a skyroof), can use it up to 2 months at a time overseas, can pause and restart the monthly plan at any time (no contract), buy extra data if you need it, set your phone to use “wifi for phone” and it means your phone works anywhere even where there is no mobile coverage (outside of course). Consumes a bit of power so you either need to plug into a leisure battery or similar - or mains - when not driving. Download speed is 150 mbs and upload around 20 (faster than our home cable). You can program it to switch off during bedtime to save power. Really is a no brainer in the bush.
