O2 is a cellular service provider operating in the United Kingdom. O2 operates a third-generation, or 3G, Global Systems for Mobile Communications cellular network that offers high-speed Internet connectivity with compatible phones. Before you can use your phone to access the Internet, however, you have to program your phone to operate on O2's network.
Insert the O2 subscriber identity module, or SIM, card into your O2 phone. In most cases, locate the SIM card compartment by removing your phone's back cover and battery. If you can't find the location of the SIM card compartment, consult your phone user's guide. Slide the SIM card into the SIM card compartment.
Replace the battery and back cover, and turn the phone on.
Check your phone's messaging application. After inserting the SIM card, O2 automatically sends you an e-mail with instructions for setting up your phone on O2's network. If you didn't receive the text message, open the messaging application on your phone. Select the option to create a new text message and text "Active" to "2020." After receiving this text message, O2 will resend the instructions for setting up your phone on O2's network.
Open the "Settings" menu on your phone, and select the "Internet" option. If you can't find the Internet settings option or if your phone labels this option differently, consult your phone owner's manual.
Enter "wap.o2.co.uk" under the "Access Point" option if you have a postpaid O2 plan. Enter "payandgo.02.co.uk" under the "Access Point" option if you have a prepaid O2 account.
Enter "188.8.131.52" under the "Gateway (IP) Address" option for both prepaid and postpaid accounts.
Enter "o2wap" under the "Username" setting if you have a postpaid O2 account. Enter "payandgo" under the "Username" setting if you have a prepaid O2 account.
Enter "Password" under the "Password" setting for both prepaid and postpaid O2 accounts. Your phone is now set up to use the Internet with O2's cellular service.
