Tried O2-SIM in 5200
My SIM of 5200 in germany is now also disconnected, some weeks after having the messages (mail and ondevice).
I turned powered-off device display down on table, then pulled off the small sticker besides the SDcard slot and pulled out the white vodafone nano SIM gently with a saftey-pin by sticking in the top of the card (there is no usual spring loaded push type mechanism) . Contacts are on the bottom and reinsert cut corner first when putting in other nano sim card.
Now I tried an O2 nano-SIM (german E-Network) having startup-PIN removed in a mobile phone and sucessfully tested for 2G-only connect and data recieving on that mobile phone.
o2-SIM is recognised successfully on the 5200 TomTom - About/Info the "SIM ID" is the correctly listed as the O2-ICCID, but GPRS-Status is still "DISCONNECTED" and Dataconnection is NONE (I also disabled BT and WIFI Connections to prevent side effects).
Has anyone successfully tried an other mobile-network than the one used by TomTom (which is vodafone in germany) and could it really be the APN problem as for O2 it would be "internet" and for vodafone it seems to be "web.vodafone.de"? TomTom should at least let us change the APN in the menu so we can pay ourselfs for the service we already paid tomtom for and they disabled just to cut their own costs.
I know there is a successful attempt with a vodafone-prepaid (
