Since I updated to iOS 11.4.1 my iPhone X attempts to use dial assist for mobile numbers which start 07. The calls then fail with unknown number. Any number in my contacts that's stored with +44 works fine. If I switch dial assist off then the 07 numbers work.
I did the firmware update while in Ireland so I'm wondering if the phone thinks it's in Ireland. I've checked and the region is set to UK.
Sorry to hear that you are experiencing an issue with your iPhone X dial assist. Did you find a solution to this?
I can see that this has been reported to Apple, but you'll need to contact them direct here for further support on this: https://support.apple.com/ unless anyone on the Community can recommend an alternative workaround. I'm not aware of one.
Hi Fraser4, just wondering if and how you resolved this? I just returned from Iceland and got a message from Virgin to follow a link to set up my iOS device for internet. Upon doing which somehow my phone then displayed all UK numbers in an incorrect format (2, 3, 2, 2, 2 digits instead of 5, 6) unless they had the +44 prefix. The phone then wouldn't dial the number saying it wasn't recognised. No joy on calling Virgin or using the text service who I don't think fully understood and claimed the problem was with my phone and nothing to do with their settings but that is rubbish of course as the problem only happened after the update and return to the UK. I have turned off Dial Assist and it now can call the numbers although they still display incorrectly and not sure how to correct that unless I amend each and every contact to the +44 prefix. Frustrating so would be interested to know what happened for you My phone is an Iphone 8 with 12.1.3 software.
Teabag, thank you for that! After 2 long evenings spent trying to get someone at Virginmedia to help or even understand the issue I now know I was not going mad and it is a common issue. That said I have had iPhones for many years and this is the first time I have experienced this one! I believe it is due to the code a country sends when you are roaming abroad and that it somehow made my phone think I was now in that country despite the region set correctly in settings. I had already turned off dial assist. A quick change of region to Belgium then change back to UK did the trick. All numbers now formatted correctly.
