It seems text messaging is the main way people choose to communicate now a days so let's see what might be causing that! In the attempt to narrow down the issue, I would recommend you send a text message back to your own number to see if it is also delayed. If the issue only happens from a specific person or persons it may be something with that carrier. If you also have the same issue when you send a text to yourself, I would recommend deleting any message threads you have in your inbox to make sure its not a memory issue. You could also test your sim in another phone to see if the issue follows the sim.
Clearing my inbox does not solve the issue for me.
About one day a week I do not receive text messages, but I can send them. The next day some arrive in my inbox and some are lost.
T-mobile has a clause in their Terms and Conditions saying that they are not liable for disruption of service, but does that mean failure of services does NOT count as a breach of contract on their part? Because I would like to cancel my contract but don't think I should have to pay the $200 fee because I am cancelling due to failure of T-Mobile to provide a service that I am paying for.
