I contacted Smarty to se if my data only sim in my motorhome router would work in Europe. No problem they said, but you would need to buy an EU Roaming data from them for £7.00. This lasts for 3-days. After buying 4 of these £7.00 EU roaming datas, I had no internet signal for 20-days, and so could not get any internet and couldn't work. I contacted Smarty on more than 10 occasions informing of my problem, only to have a BOT keep asking for my personal details and telling me to turn off my Aeroplane tab. I kept replying that i don't have a phone, I have a router with a Smarty Sim. No-one contacted me, apart from these BOTS, so it was a hugely frustrating time for me and I have since cancelled my contract and will try to go with a provider that can at least answer a phone call to help with difficult situations. Terrible, terrible service; great if it works, but not when it doesn't. Bye Smarty
