If you send an SMS message to a friend who doesn't receive it after a couple of hours, you may want to try again. Text messages can be a little flaky at times, and occasionally encounter some delays before reaching their recipient. If you see a message telling you that 'Something went wrong,' it could indicate that your message is taking a while, or that it might not go through at all. So, your best bet in this case is likely to try again.
