Here is the background to dialing in from GPRS.
(The same applies for GPRS and EDGE, depending on your handset and coverage)
FIRST STEP - TEST
I recommend making a wap connection from the handset first as that establishes that you are provisioned and that the GPRS 'APN' works.
If this doesn't work go to 'SELF PROVISIONING' which ensures you are provisioned for GPRS/EDGE and also sends you a CONFIGURATION string.
All postpaid users are preprovisioned for GPRS, EDGE and MMS. Occassionally the setting may be lost due to some service provider process or customer request. In that case follow the instructions for prepaid.
Prepaid users are not preprovisioned and need to provision themselves.
SECOND STEP - TRY THE QUICK DIAL-UP
Try the dial-up string *99#
If you are lucky this will work first time.
The reason is that MTN is set to default to the correct APN if not supplied any information. However different handsets send us different things so cannot be guaranteed to work.
There are a couple of customers that have problems with their devices because some devices fail if they are not configured with an apn.
Also try *99***1#
If this does not work, you need to get into some detail.
SELF PROVISIONING and AUTO CONFIGURATION
The following steps do two things - they ensure you are provisioned and send configuration.
Type in *123*1# (free service) and press send and you get back a prompt. You choose wap settings, mms settings or both. You are provisioned on the network for these services and sent a confirmation.
If you request configuration settings, these are also sent to your phone. They work for most handsets (especially the newer ones) but not all. Some you must set manually.
THIRD STEP - TRY THE DIAL UP AGAIN
The handset stores a list of APNs you have set. An APN is a destination in GPRS. For example on MTN, both the 'internet' and 'MyMTN' APNs are for general internet access. MyMTN is preferred if you ever want to go overseas.
You can either set the APN manually, set it via auto-config (as explained above) or set it by your computer (if you have a cable or link) using an AT command.
The dial-up instructions depend on what APNs you have in your handset already. Some MTN handsets are pre-set with wap and mms settings. You also have the settings you have set yourself, other settings (perhaps from a previous operator) will still be on your phone.
You can see these settings manually via the handset menu. If you use the modem diagnostic feature from Windows you can query the modem and get back a list.
The AT commands to query this are (eg from hypterminal) are
AT+CDGCONT? OR AT+CDGCONT=?
The APN list is called a PID. PID 1, 2, 3 etc. Can also be called CID.
There seems to be no clear logic as to how handsets relate the list of connection settings to the PID numbers - the third setting may not be PID=3. They are numbered up from 1 but the order seems to vary. Also handsets do not necessarily let you know what the PID numbers are. The query from the notebook is more accurate.
If *99# does not work, then try *99***1# as the dial up. This uses the first APN stored in your handset.
If you use *99***2# you use the second one ETC.
Can set up via hyperterm or a config string (modem initialisation):
AT +CGDCONT=1,'ip',internet
You can use any username you want (or blank) except MMSUSER or WAPUSER
Getting into the MMS APN does not really happen and here's why: The MMS setting on the handset is a combination of the myMTN APN as well as the username MMSUSER and a password. The WAP settings are the same myMTN APN with a username WAPUSER. Internet settings are the same myMTN APN with any other password. If you dial from your notebook the handset/modem can use the myMTN APN which you set up for MMS (if you really want) but it uses the username and password from your PC rather than the one on the handset. It appears you are getting into the MMS area but I do not believe you are (unless someone here is going to prove otherwise)
