Gang, The verdict on this is out! Turns out the SIM cards work just as they would at home! I've verified this physically.....down to the IP addresses assigned to them! I had consulted 2 other friends in 'knowledge street' and got these verbatim responses that may be of interest to some members... =============Knowledge Street1=============== *The APN is only known in your home network. * *The serving SGSN, visiting SGSN has to connect to your home APN DNS to resolve the APN so as to get which GGSN to create your session so as to obtain IP services. **Once the request is received by your home GGSN, the rest should just flow: IP address, billing, etc * =========================================== =============Knowledge Street2=============== *When you roam you will be attached to the SGSN in the foreign country, but the routing shall be done on your home GGSN; meaning that you will have an IP from the range provided in the roaming country* *Before attaching to the foreign SGSN, the foreign network does a check with your home network - subscriber validation.* *Since the routing shall point to your home GGSN which basically routes your APN range of IP's accordingly, you should be routed as if you were at home... also depends on the "APN related priviledges"* =========================================== Now we know. :-) :-) Tony. 2017-02-21 17:54 GMT+03:00 Odhiambo Washington <odhiambo@gmail.com>:
Tony,
Without thinking so much about this and asking what it is you do with the IPs, I must say IP addresses are NOT portable outside a given network where they are assigned. You cannot say in Kenya, Zuku assigns you 1.2.3.4 routed for the purpose of some obscure services that you run in your Kenyan network and then expect to carry the router configured with Zuku IPs and still expect it to work in Safaricom network, for instance! Now extrapolate that to a foreign country.

Good people.... small query here....that little GGSN & SGSN matter...
1. My mobile Phone Service provider issues me with a special APN SIM card (assigned a pre-defined range of IPs)
2. I roam on data into a different country...
Who assigns me the IP when in the foreign country? Is it still my provider? And will I still be assigned an IP address in the pre-defined range I'm used to at home?
Mwagiru, Kioko et al.... SOS!
Tony.
