I was traveling through London mostly and because I had previously used a matrix sim, I stuck to that only. Knowing the extent and the kind of services that I had experienced the last time, sticking to them was more reassuring of the uninterrupted network. Their plans especially for London are quite affordable and better than what I had seen there as well. I accidentally had to extend my stay for another 10 days in London, to which Matrix team catered to by not disconnecting the number and extended their services beyond the agreed date as well. Great services, easy pricing! Always travel with these guys 😊
