How to send a short message to Pakistan

That's right.

Sending a text message is a country code plus a mobile phone number. Numbers in Pakistan usually start with 03, so you should remove 0.

It's cheap to call China from Pakistan, less than 30 cents a minute, but it's expensive to make domestic calls.

Sometimes you can't get the message.

It is best to contact customers by VoIP or send emails.

I work in Pakistan. I can send messages if I have any questions.
