We got the errors in my campaign
Some of your ads may stop running Phone numbers are no longer supported inside ad text or sitelinks extensions. Some of your ads contain phone numbers and will stop running at the end of July unless you make changes. To help customers call you directly from your ad, please use call extensions instead.
Re: We got the errors in my campaign
Yes this is true.
Adwords will no more serve ads with phone numbers displaying on it, neither sitelinks with phone number will display. You can start using call extension, which is suggested as an alternate for diplaying contact number with ads in search network.
Have a look at the policy for using call extension first and then set up the same: https://support.google.com/adwordspolicy/answer/1054212?hl=en#
