It is noted that errors due to networking, connection and some kinds of mistyping of URIs are not within the control of the content provider, which has no way to influence how such errors are presented to the user. However, where errors are within the control of the content provider the user should be provided with clear information regarding the fault they have experienced. This should help them to understand whether the fault was temporary or permanent, whether they should retry the attempt to access the content and how they may be able to escalate the problem.
Mobile phone area codes in the Philippines are composed of three digits and always start with the number 9. Originally, there were only three prefixes or area codes used for mobile phones: 917 for Globe Telecom, 918 for Smart Communications and 973 for Express Telecom, the three existing mobile companies at the time. As service grew rapidly throughout the 1990s and even until today, existing codes have been exhausted and new codes have been added to fulfill demand.
