I tried searching the archives<http://www.google.co.ke/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&q=site%3Amy.co.ke+zain+service+unavailable&btnG=Search&aq=f&aqi=&aql=&oq=&gs_rfai=>, but didn't get any information. Forgive my ignorance, I'm new to the market. I'm using a Samsung GT-S5233A to try and browse, and was getting "No response". I called Customer Care three times, and they say they've activated data on their end. They were supposed to send me new settings via SMS, and I'm still waiting. The only thing that has changed is the error message, now "Service Unavailable" in South C. No response from the customer care email address either. The phone is set to "Zain WAP"; Access name; wap.ke.celtel.com Auth type; Normal User ID; wap Password; <left blank, per Customer Care, new password doesn't work either> Any help will be appreciated. Asante. Erick
