Your post is a bit confusing.
What does "my service in keep dropping" mean?
When was everything working ok last?
What changed in the meantime?
Are your APN settings configured correctly?
Are incoming/outgoing calls and texts working ok?
Do you have an active membership plan in order to be able to use outgoing services?
If you keep having issues then maybe try a replacement SIM in case that helps at all?
Unfortunately I may be wasting my time because you never followed up on previous queries of yours that I responded to giving useful suggestions and asking for further clarifying information in an attempt to help so I expect the same here...
