Updating sms

The first action plan of the CEPT Group GSM was approved in December 1982, requesting that, "The services and facilities offered in the public switched telephone networks and public data networks ...should be available in the mobile system." The GSM is optimized for telephony, since this was identified as its main application.Let’s review those possible reasons and then cover some troubleshooting steps.Before proceeding with troubleshooting, let’s cover the most obvious service related reasons why an i Phone won’t send a text message: It’s pretty obvious when a text message doesn’t send (or i Message too), you’ll see a little red (!Of course, sometimes the i Phone won’t use the i Message protocol even if the sender is on an i Phone as well, particularly if the recipient is out of service area or has turned off the i Message service for some other reason.We’re not really focusing on i Message here though, we’re focusing on the standard text message protocol instead.Typically transmitting an SMS text message is very reliable, but sometimes an i Phone won’t send a text message, and in such a situation you’ll likely want to troubleshoot the problem.Keep in mind that most i Phone users communicate with other i Phone users with the i Message protocol, which is signified by the blue message bubbles (as opposed to the green bubble which signifies SMS / text messaging).



Resetting network settings can be a pain because you lose wi-fi passwords and custom DNS, but it can also be a cure-all solution for many common networking issues with i Phone, including the inability to send messages.

The key idea for SMS was to use this telephone-optimized system, and to transport messages on the signalling paths needed to control the telephone traffic during periods when no signalling traffic existed.
