It appears as if there’s currently an issue with Telus WAP service on both CDMA and HSPA networks.
Upon launching the web browser, users will get a “403 forbidden” error message. Some users are also getting “invalid proxy” error messages.
Based on the conversation with the Telus customer service rep, Telus has identified the problem and is working on it to resolve it.
Update: As of 9:00am Eastern, according to Telus the issue has been resolved. You may want to perform a battery pull to get your phone working.
