Text messages in TRIPLICATE??

[dauber]

So...my wife has an iPhone 5S, and I have an iPhone 7. I don't know about hers, but mine is running iOS 10.3.1. Since yesterday afternoon, when I send my wife a text, she gets it three times. Three separate messages. And once she even got a gibberish text from me that I didn't even compose.

Neither of us has iMessage enabled. We're both on the same plan with the same provider (AT&T). It's only my wife who's getting triplicate messages from me, and she's getting triplicates from nobody else. A power cycle didn't solve the problem.

So...what's going on, and how can I fix it???

Work by elimination: Put one of your SIMs into another phone and retest. If the issue persists, put the other SIM into another phone and so on. You could even start by putting your SIMs into eachothers phones. The above process will tell you where the issue lies.
