My SIM card is blocked, what happens to inbound SMS messages?

If your number has been cancelled, the sender will probably get a "message sending failed" type notification on their phone when they try to send the message. It doesn't sound like your number is cancelled, because otherwise you would get a "number not available" or "number does not exist" message when trying to call it.

If your number has not been cancelled (e.g. if O2 are keeping your account open and are going to send you a new SIM for the same number), then the following may apply:

When someone sends an SMS message, it has a "message validity" time attached to it. This tells the SMS centre how long to keep attempting to deliver the message for. After the validity time is up, the message will simply be deleted (usually without notification to either the sending or receiving party).

The value of the validity period is set by the sender's phone, and can be manually altered if they want to give it a shorter or longer time for delivery. For instance, if a message will be irrelevant after an hour, they could set the validity to 1 hour so if you haven't got it by then, you never will.

Generally phones seem to give SMS messages a validity of one or two days if the user does not choose a different amount of time.

"If I try and ring my phone" Just ring it man don't be shy or are you one of those guys who get really..

"I get an unobtainable tone" Plucked up the courage I see

Enough... As I have the answer, I think I will be forgiven

Answer. In your sms settings you, me all of us have "message validity" which is normally set to 24 hours and can be changed to lower or higher time.

If one of you friends has not changed it 24.01 later message is gone for good

If another one of you friends has changed it to a week (maximum?)" then if you get back your phone before that week you will receive it

It is down to what the senders later "message validity" is set to initially and if your phone is on
