Went to tmpoint tis noon for 8mb upgrade, but duno can support or not , need the technician to check snr, and bro u dont need to w8 till ur nx bill cos they will divide the usage between ur curreny plan n 8mb plans for ur nx bill.

Smart but, u need to terminate ur current line before apply for new1. And also new application new contract, and wat if after u terminate ur 4mb then ur place cant support 8mb ? And tm dont wana open new port. U can try but i think sc will just ask u to upgrade.
