My old number from o2 has transferred across to ID mobile but my problem is when i message my contacts, by SMS or whatsapp, the receiver gets the SIM card number that came in the post.
Calling my contacts works successfully in terms of they see its me, my old number, but not when messaging. Why is this? and please advise ASAP.

I've sorted it now by uninstalling WhatsApp and reinstalling it, then putting my old number in.
