Enable MMS for tmobile iphone 5 with 6.1 ios?

Hey so i just updated my unlock iphone 5 to ios 6.1 and enter all the APN for MMS. Everything works fine but the picture MSG. I can receive picture msg but i can't not send? It always stop arpund 95% anyone kno how can i fix this?

Try turning off Wi-Fi. IPhone MMS is almost completely incompatible with T-Mobile. Your best bet is to use a MMS app that uses data/Wi-Fi, not the paging channel.

Don't listen to people like SSP Bowl Dude, they don't know what they're talking about. I have MMS and other things like tethering and 3G working fine with my iPhone5 with Tmobile in Florida.

You can enable MMS by going to Settings->General->Cellular Data Network and changing the following settings.

MMS

APN epc.tmobile.com (be sure you don't use the hyphen between t and mobile on this one)

Leave Username and password blank

MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc (be sure to use the hyphen this time)

MMS Proxy: 216.155.165.50:8080

MMS Max Message Size: 1048546

MMS UA Prof URL: http://www.apple.com/...uaprof.rdf

If you are paying for tethering through the carrier you need to change this

Internet Tethering

APN pcweb.t-mobile.com
