Beware - Although excellent value and perfect for occasional users or an emergency phone Customer Service is non-existent. So if you have any queries, complaints or just want advice no chance! All forms of contact - phone, email, even Chat robot do not respond. Look in detail at all the 1 star reviews.
** UPDATE - After 3 days eventually managed to get someone to answer both phone & email, so solved my problem. If customer service was improved 1p Mobile would be the best out there for a light user.
