Relating to your query, is the phone that you're using under a contract or is it a pay as you go phone? Have you checked the settings on your phone? Basically, if this phone is under contract with any network operator, you should have there already the access point or the internet setting that you need for the phone. It includes the MMS settings that you needed. If this can't be found on your phone, you need to contact your network operator and ask for the settings for the phone. Then you just need to manually put all things on the phone under Settings > Access Point > Add. Kindly follow this instruction and let us know if this one resolve your concern.
