"Unknown sender" when importing MMS messages #213
Comments

Quick update: it looks like this has to do with the sub_id. My backup has 3 distinct values (-1, 1, 2), and on the new phone, the only valid sub_id is 1. If I use the default setting to ignore the sub_id when importing (which overrides sub_id to -1), all the messages import, but this unknown sender issue shows up. If I disable the option, such that the sub_id is NOT ignored, the messages with sub_id: 2 disappear. The correct sequence that seems to avoid both issues, is to manually find and replace all values of "sub_id" to a valid value for the device (in my case, 1) and enable importing with sub_id. So to wrap up, it seems overriding sub_id to -1 (the default behavior) isn't without side effects. Possibly the more reliable option is to instead override with the current SIM's sub_id (in my case, 1). Would it make sense to allow specifying the sub_id override as a preference if it can't be easily / reliably detected? Or is it probable it would just introduce a different issue? |

Thanks for reporting this. The solution turns out to have been simpler than anticipated: While previous commits provided for setting the |
I'm on the latest stable GrapheneOS (Android 14) with a Pixel 7. I'm importing a SMSIE backup made with 2.4.0, using 2.4.0, and struggling to get MMS messages to show a sender. On both the backup and restore device, I'm using Google Messages.
All the messages import successfully (everything else looks good), and the entry in messages.ndjson looks good at a glance, but MMS messages directed to me (which are usually to multiple people) show up in Google Messages as "Unknown sender". I also checked with Graphene's default Messaging app, and the info on the message says "From: Hidden sender address".
Here's one of the messages giving me trouble (formatted, plus phone numbers and a few IDs redacted). The original phone numbers are in the same format of 10 digits, no spaces or non-digits:
{ "_id": "43897", "thread_id": "43", "date": "1726518279", "date_sent": "1726518275", "msg_box": "1", "read": "1", "m_id": "RED000000000000000000000", "ct_t": "application\/vnd.wap.multipart.related", "ct_l": "http:\/\/RED.D0.00.00\/servlets\/mms?message-id=RED00000000000000000000001", "m_cls": "personal", "m_type": "132", "v": "16", "m_size": "767", "pri": "129", "tr_id": "proto:RED000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000", "d_rpt": "129", "locked": "0", "sub_id": "2", "seen": "1", "creator": "com.google.android.apps.messaging", "text_only": "1", "__sender_address": { "_id": "150429", "msg_id": "43897", "address": "6666661111", "type": "137", "charset": "106", "sub_id": "2", "__display_name": "Alice" }, "__recipient_addresses": [ { "_id": "150428", "msg_id": "43897", "address": "6666662222", "type": "130", "charset": "106", "sub_id": "2", "__display_name": "Bob" }, { "_id": "150430", "msg_id": "43897", "address": "666666333", "type": "151", "charset": "106", "sub_id": "2" } ], "__parts": [ { "_id": "62277", "mid": "43897", "seq": "-1", "ct": "application\/smil", "name": "smil.xml", "chset": "3", "cid": "<smil>", "cl": "smil.xml", "text": "<smil>\r\n <head>\r\n <layout>\r\n <root-layout width=\"240\" height=\"160\"\/>\r\n <region id=\"Image\" width=\"100%\" height=\"67%\" left=\"0%\" top=\"0%\" fit=\"meet\"\/>\r\n <region id=\"Text\" width=\"100%\" height=\"33%\" left=\"0%\" top=\"67%\" fit=\"meet\"\/>\r\n <\/layout>\r\n <\/head>\r\n <body>\r\n <par dur=\"8000ms\"><text src=\"text.000000.txt\" region=\"Text\"\/><\/par><\/body>\r\n<\/smil>", "sub_id": "2" }, { "_id": "62278", "mid": "43897", "seq": "0", "ct": "text\/plain", "name": "text.000000.txt", "chset": "106", "cid": "<text.000000>", "cl": "text.000000.txt", "text": "Sure I'll probably just be reading most of the evening lol when do y'all usually wrap up?", "sub_id": "2" } ] }I tried the import process several times, each time wiping all messages and clearing cache / storage for each messaging app. I'm using default options in SMSIE to import.
It seems like the sender address is not being set/imported, though it does look like that attribute was backed up. Any ideas?
