Re: No notifications when I text myself
Yes, it is useful as a diagnostic. I noticed 5G service handoffs can be flaky sometimes. If the SMS test doesn't work, you can switch your phone to airplane mode and back to bring cell service back online. Another use case is to test on an airplane while WiFi calling is enabled and you have WiFi. On some flights SMS works over WiFi and on others only messaging apps do. It is good to know what works on a long flight. It isn't critical, but you wonder why a simple loopback test is now prevented. It is almost always supported in any communications equipment for basic diagnostics.3Visto0likes0ComentariosRe: How to fix significant delays of messages sent using the email to SMS service?
Update after calling 611. Got some useful information. In my use case, the SMS is sent through an email gateway. Unfortunately, spammers are using this facility to spam general users, so TMobile has implemented a filter. Here were takeaways. Use a short code to send SMS (this is supported; the email gateway is best efforts). When spam volume subsides, delays should reduce. Signatures, etc in email headers do not help make it past the screening process any faster. The spam screens will still inspect the messages, which can take some time.12Visto0likes0ComentariosRe: How to fix significant delays of messages sent using the email to SMS service?
I called 611 and spoke to a support rep. In my use case, the email is being sent to ###@tmomail.netfor business notifications. It turns out that this gateway is being exploited by spammers to send bulk email, so T-Mobile has installed a spam filter, which can fall behind. Some takeaways: Filtering was installed recently, around July. Migrate to short codes, it is better supported. Methods for authenticating Email (to avoid getting caught in spam filters) won't prevent it from being scanned. If spam levels decrease, the service should become more responsive. This method of sending SMS is considered unsupported. Hope this helps folks.11Visto0likes0ComentariosRe: How to fix significant delays of messages sent using the email to SMS service?
Just banged my head trying to troubleshoot this issue. Messages are accepted by T-Mobile's server and a MessageId is provided. However, delivery occurs anywhere between instant and 24 hours. The issue is definitely on TMobile's side. Planning on calling 611 to report the issue. They'll prolly start by telling me to reboot my phone and update network settings, even though this issue has nothing to do with my phone …. will report back how it goes or if it dies at their L1 support.15Visto0likes0Comentarios
