I bought one of these sim cards to use with a TP Link 4G router. The router arrived but the sim was missing from the package. I received an immediate refund from Amazon without any issues and ordered another. I put it in the router and it worked immediately. I live not too far from a mast and receive a good signal and am getting over 60mb download. I have been looking for a decent alternative to Virgin Media as I am fed up with their woeful customer service, constant unjustifiable price increases and the feeling tha I am simply not valued as a customer. If the router continues to perform well I will be dumping Virgin. Lebara uses Vodafone so coverage is good and I am pleased with the Lebara App which gives easy access to top ups, the amount of data used and other information. I see they have a deal at the moment for unlimited data at £22.50 per month for a 12 month contract. I don't use the internet for gaming but do use Netflix etc so the download speed I get from the router/sim are fine for me and at the price the Lebara unlimited data package is a lot cheaper than BT for the same speed. I will be testing the router and sim over the next few weeks but so far am very pleased and Lebara does seem good value.
