No services

Hello friends,

I am from India, currently working in Northampton.. I am using Lycamobile network.. I couldn’t use my services since midnight because it’s displaying No services and if I try to search networks manually, it’s futile as it is just searching.. I bought the phone from india and is using it without problems in uk for past 7 months.. Kindly help me out of it as I am losing lots of important calls..
