I know there have been multiple threads about this, but I've found some settings that actually worked.
WIND's APN listings on their website apply to Windows Phone 7 devices only, and will not work on WP8 handsets. For those with Samsung ATIV S (and possibly HTC or Nokia devices who have flocked to WIND), I've found these settings from Mobile Carrier Settings for WIND - Canada that worked like a total charm. Where WIND would say to leave certain fields blank, you actually need to input more information.
Tap "Add/Edit MMS APN"
Tap APN and type mms.windmobile.ca
Tap WAP gateway (URL) and type in 74.115.197.70
Tap WAP gateway port and type in 8080
Tap MMSC (URL) and type in http://mms.windmobile.ca
Make sure IP Type is at: IPv4v6
Tap Save
I just sent a test MMS and worked perfectly. For other WIND users, please confirm if this fixed your problem.
EDIT: Some other things to troubleshoot if these instructions don't work:
- After putting in these settings, if your MMS comes back with an error, reboot your device either by powering down, or removing the battery. I had to do this when my temporary number was scrapped in favour of the number I had ported over.
- If your network is on "automatic" you may have to choose the network manually. That allowed me to send any MMS without problem.
- For the SGH-T899M, by default it will have the fastest connection speed set to LTE (could also read as "4G"). You may have to change that to HSPA/WCDMA (or "3G").
- WIND's maximum MMS size is only 300 KB (yikes). So if you try to send certain files, but your device tells you that it can't attach it, then that's a carrier restriction. There's nothing "wrong" with your phone, or your MMS settings.
I'll add other suggestions as they come up.
