Numbers sometimes not recognised

[IanJone_2515436]

Is anyone else having this problem.

Numbers I tell regularly sometimes they say this number is not recognised. The numbers are saved to my phone. This morning I tell someone and then needed to tell them back and it says number not recognised 

[MSF]

@IanJone_2515436 Have you tried taking them out of Contacts, dealing the number again and then storing it fresh into Contacts?

I am wondering whether perhaps there is a corruption in your contacts somewhere?
