Using a Registry Editor edit the following values:
[HKEY_LOCAL_MACHINE\SOFTWARE\Arcsoft\ArcSoft MMS UA\Config\mm1\WspHeader]
DELETE KEY -> "X-sprint-MDN" or rename and use the next line below...
ADD STRING -> "X-metropcs-MDN"="XXXXXXXXXX" ( Insert your 10 digit phone Number )
ADD STRING -> "X-DEVICE-MIN"="1XXXXXXXXXX" ( Insert your 10 digit phone Number WITH the 1 in front of it )
PS YOU MUST HAVE YOUR INTERNET UP AND RUNNING BEFORE TRYING TO GET MMS OK THANKYOU
