Today ,There is a new job to do for me after I had just finished the old job(IR21 Documents).
The job that I did was checking foreign operator's sim cards that was used for international roaming.
Check the sim card for what?
- To make sure the sim card can be used and to protect the mistake of the connection of the international roaming between foreign operator and AIS corp.
How can we check it out?
- For each sim card, Pick it up one then push it into the mobile.
- Wait more and more until the "AIS GSM" text appear on the display of the mobile. (By technically the text will appear if and only if the location update process done. )
- After that we have to make sure the sim card can be used by put the IMSI and MSISDN of its to the system. If no mistake, we will see some information and services that sim card can be used. But if not, we won't see that on the screen.
*So why it happened?
There are many cause such as the sim card was close by the owner operator or may be the mistake of connection or the deal is over between AIS and the owner operator.
*What we gonna do next?
Make sure again by make the outgoing call to the other one. If it can be reach, that sim could be used and a cause of the mistake may be the location update process is not complete. But If not, the sim cards cann't be used.
End and enjoy with my suck english writting LOL555.

Morning 8:37 6/4/51.
I was introduced to AIS services such as one sim two number. The main idea about that concern for MSISDN,IMSI.
First, I please to explain the word "MSISDN" and "IMSI".
From wiki, MSISDN is a number uniquely identifying a subscription in a GSM or UMTS mobile network. IMSI is a unique number associated with all GSM and UMTS network mobile phone users.
As wiki said above ^. Someone may not get anything.
I please to make abstraction to tell you.
MSIDN = Mobile(Cellphone) number.
IMSI = identifier for each sim.(Global,standard)
So one sim two number mean to use two MISDN in one IMSI.
Now,what if I use one sim two number service?,Let's see what's going on.
When I call to the other by use USSD#(*200#). After that the MSC will query my profile at HLR then it's looking for all my services ,After a while it found that I am using one number two number service and then the HLR will reference to the record of the other HLR which I activated second MSISDN.
