Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Are you sure that the 2.0 GB that you are apparently limited to, is not the storage limit for files in the memory of your Samsung Galaxy device?
To check on whether this is a limit on data transmission (different from data storage, of course), you would need to contact our phone service provider or the data carrier for your phone, identify yourself and your account, and ask hem to check as to how much data transmission - and in what forms, texting, pictures, attached files on emails, emails, phone calls - your current service plan allows.
Let me know, please, the details of the apparent 2.0 GB limit. I will help you get a higher limit if I can.
