Unfortunately you haven't posted which device you are using as there are available applications for the higher end S60 devices.
Happy to have helped forum in a small way with a Support Ratio = 37.0
With the Nokia 5070, it being an S40 based phone with limited capabilities, there is no way to block calls or SMS.
If you had an S60 based phone, there are applications that can make incoming calls from certain numbers not ring at all, or deletes messages from specific numbers as they come in.
With an S40 phone like yours, such applications cannot be written.
So, change your number (get a new SIM card), call back or text the other people and ask them to stop calling or sending you messages.
Or ask your network operator, if they have some sort of a blacklisting service, where the network blocks calls/messages.
You can also tell the other people who use your phone, that unknown people (assuming they really are unknown) make calls and send messages to you, and you can't stop it.
First of all I would like inform that I not a person seeking help regarding the subject, still I just went through your above post which I feel is very nicely explained and so useful, you explained it in such a way that even though the persons phone is not capable for a solution to his problem and you did'nt told him "NO". You have given him so many options which he will be knowing but your msg have made him to think once again.
I really appreciate you for such a wonderful post.
Keep it up, Good Job.
Refer petrib's post above.. Your phone is also as S40 device...so not possible.
i have an s60 based phone.
So please can you tell me which applications should I use to stop the bulk SMS.
There are a lot of sms blockers available at the OVI Store...Just search for 'SMS Blocker' or 'SMS Filter'...
