Cambodia has traditionally only two official gateways for international telephone calls:
- 001: Ministry of Posts and Telecommunications (MPTC) / Telecom Cambodia (T.C.)
- 007: Royal Telecam International (RTI), subsidiary of MobiTel, also known as TELE2
Calling through either of these gateways is very expensive (usually more than one dollar per minute).
Fortunately all GSM mobile phone network operators in Cambodia have introduced a cheaper alternative for making international calls. It is often based on voice-over-IP (VOIP) technology. See the table below for information about each operator: Continue Reading »

This time I decided to have a look at the peering relationships of various Cambodian internet service providers (ISPs). The data is based on several BGP routing table snapshots from various international sources during about a week in the middle of December 2009. Continue Reading »

The “magic” short code for checking the balance/saldo/credit of a pre-paid SIM cards is different for each and every mobile phone network operator in Cambodia. See the table below: Continue Reading »

I was previously using Project Honey Pot’s http:BL in conjunction with Bad Behaviour WordPress plugin to control access to this blog. My intention was to restrict access from malicious spammers and content scrapers.
Unfortunately it seems that plenty of Cambodian IP addresses are on various blacklists and thus many legitimate users were blocked as well. Continue Reading »

Recently I wrote an article on internet development in Cambodia. When looking at the statistics in that report, it appears as if Cambodia did not have internet connectivity before the year 2001. That is not the case. Continue Reading »

This time I decided to have a look at the internet service provider market in Cambodia. It is not long since there were only couple of operators in the market.
Nowadays there is plenty of ISPs to choose from. In this report I am considering any organization which is a member of APNIC and which has allocated resources from them as an ISP. Some of the smaller ISPs might not be included in case they are only re-selling capacity provided by their Cambodian up-stream ISP.

Pros Thom has compiled a simple comparison of call rates of different mobile phone network operators in Cambodia.
There is no exact answer to the question “which operator is the cheapest one?” as it all depends on several factors; like what types of calls you make, at what times you make the calls, what kind of promotions are utilized, how expensive charge cards you use and so on. This comparison makes some generic assumptions on these matters.
The general outcome of his comparison is that Beeline is the cheapest in most cases.
Have a look at his comparison at the following URL:

Recently I had to choose a free open source e-commerce platform for one of my projects which involved setting up an online store. After some research and lots of reading of various forums and blogs, I identified the following shopping cart software packages to be most recommended by other people:
Why does the security matter?
One of the main concerns when setting up an online store should be the security of the store. You do not want some malicious person to steal all your confidential customer data, divert your customers’ payments to their own account or mess up your site. You can also have your site easily black-listed by the search engines if someone injects some malicious code in your site. Many webmasters do not seem to be too concerned about this. They install a shopping cart software and purchase a SSL certificate and think that they are fine because they have the SSL enabled. Many on-line shoppers seem to think that way too. This does not help at all if someone breaks into the server which is running the software.
After the shopping cart software has been installed it is way too often left unmaintained. That kind of practice is just asking for trouble beacuse one day someone will find a security hole in your chosen e-commerce platform. You need to closely monitor relevant security mailing lists or web sites to be able to quickly notice when you have a problem and to fix it swiftly. Obviously this does not apply just to the shopping cart software, but you need to be aware of vulnerabilities in any underlying software (like the web server, PHP interpreter and operating system) as well as any third-party add-on modules or plugins.
