Globally default GPRS, MMS and WAP settings
Device management is a real pain in neck in GPRS/EDGE.. Why dont cellular industry and handset manufacturers adopt a default GPRS, MMS and WAP settings preconfigured in handsets and supported by GPRS/EDGE network?

Hello Aatif,
In theory it is possible for the cellular industry and handset manufacturers to adopt such settings, but it will never happen.
The problem with settings in GPRS, MMS and WAP , and same for 2G and 3G services is in the configuration of the Access Point Name in all PS data capable devices and in particular the cases happening in roaming scenarios. All details about roaming are in the documents
GPRS Roaming Guidelines ir33, ir34, ir35. Here is the summary:
In all HLR there are special flags related to GPRS (3G) roaming. The two important fields are VPLM allowed= Yes/No and APN.
The VPLMN flag allows the roamer to use access points in the visited network, or in other words to connect to GPRS services (MMS, WAP, internet access) via roaming partner GGSNs. This is usually not allowed and most of operators keep this flag to VPLMN=No, except for some special cases.
APN is a field that could have any allowed by the specification combination of letters and numbers and is in fact a name to be resolved by DNS, or in case of roaming, the private GRX (GPRS roaming exchange) DNSs. In case the VPLMN flag is set to No, always after the name of the visitor APN, is appended the GOI=MCC+MNC of the visited network, in such way routing the requests to home PLMN DNS.
In short, if there were no roaming complications, all cellular services providers and device manufacturers could have provisioned the APN for internet to be "internet", WAP "wap", mms "mms", etc. according to some simple rules. Because of roaming scenarios, all operators try to make it slighly more complicated in order to avoid some fraud and have better control over the PDP context activation procedure.
Hope this helps.

they do, all technologies are enabled and considered, the only thing is you have to configure the gateway number, or enable roaming when you are out of your own country ( of course, assuming you have a phone that has all the modes, technologies, and frequencies enabled to use with services active)
