I wish more info was easily available online (eg, APN, MMS, roaming) I would gladly read them. A developer could comment, but that would take away precious time for an issue with many possible causes. I am sure the developers are busy I am busy. Many others have experienced this same ERROR, and I actually hesitated to add my comments, which just seems to add burden to the considerable existing burden (ie, 1.2k issues). I have wasted hours in debugging my issue. In my case, Signal would be a buffer against changing network - I share your frustration ever since switching service providers about two months ago.

I believe those messages would use Signal's protocol, instead of MMS, and be routed via Signal instead of the service providers' MMSC. I wonder about the situation where a group chat uses Signal exclusively.

I experienced the ERROR from both iOS and Android users, and both Signal and non-Signal users. I should verify this 100% by using Android's default Messenging app, but I think I have tested enough configurations to feel confident about my situation. In my case, the cause is essentially poor cellular coverage, possibly poor APN configuration, and most likely not due to Signal. Just to clarify, I think the widespread error in receiving MMS (ERROR) has many possible causes.
#SIGNAL VINE MMS HOW TO#
So my dilemma is how to configure APNs? Is there a way to get the higher bandwidth of Metro's network when available, backed by the more reliable coverage of T-Mobile's network, or perhaps just with MMS? I have found very little information about configuring APNs. Grrrr, I have great sympathy for those who debug networks. I kept trying several different configurations, but a working configuration would somehow fail again. This was my epiphany because I had been losing MMS messages seemingly at random. Whenever a switch occurs, network routes must be updated that is, any MMS messages in flight are lost until my phone's network route is registered. But the spotty coverage means that my phone may switch APN between Metro and T-Mobile. Then I properly configure the APN for Metro, and connection bandwidth is much better. I tested a T-Mobile device and saw what first class bandwidth looks like. Okay, so I configure APN for T-Mobile but discover that my connection bandwidth is slow, as though my data is classified as second class. The confusing part is, I thought service providers have roaming agreements such that phones can access any network, automatically, and just work, but no? However, I am allowed to access T-Mobile's network by configuring an APN. Unfortunately, Metro's coverage is spotty where I am. I had assumed I was on T-Mobile's network, but Metro operates their own network. My service provider is actually Metro, a subsidiary of T-Mobile. The summary is, configure your APN for your network. Hopefully my experiences might help others. I think I have figured out my particular issue with receiving MMS. ScreenshotsĪndroid version: 10 (just says 10) Kernel version 4.9.186-18249188
