For more than a year, more than half of the text messages I receive don’t ‘ping’ when they arrive.
All my notifications are turned on, and I only have a couple of spam callers blocked, but sometimes messages sound a tone, and sometimes they don’t, even from known numbers. Banners do work correctly.
Why do some messages sound a tone and and some don’t? Is it an Apple issue or a T-Mobile issue? Or both?
I’m using an iPhone 6S with the latest iOS and have 2-3 bars of T-Mobile LTE signal strength.
