BT Mobile and 3G iphone

Go to solution

Hi

I recently bought an unlocked i phone 3G. When I put in my BT Mobile SIM I get a message "Could not activate cellular data network".

However I also have a Tesco SIM, and when I put that SIm in the iphone then 3G works perfectly.

Please help, I would love to use 3G with BT Mobile on my iphone.

many thanks

Because BT use Vodafone's network, the Vodafone data network settings get loaded from the SIM. You need to manually enter BT's setup:

 

Settings->General->Network->Cellular Data Network:

 

Cellular Data

 

APN: btmobile.bt.com

Username: bt

Password: bt

 

MMS

 

APN: btmobile.bt.com

Username: bt

Password: bt

MMSC: http://mms.bt.com/servlets/mms

MMS Proxy: 212.182.137.012:8799

Hi

brilliant, that seems to have solved it.

The 3G signal seems to alternate between "3g" and "o". Do u know what the difference is please ?

"o" means GPRS

"E" means EDGE

 

When the 3G signal is marginal, it will switch from "3G" to either "E" or "o" to keep a data connection alive.

thanks for that advice on bt sim in an i phone unlocked from vodaphone, amazing i came here for advice having been given the run around by bt's tech team, who really did not have a clue, answers ranged from "you need a device driver" to i phone is not compatible with the bt mobile network???

so I set all the settings as you rightly instruct below and works perfectly until I step out the front door (away from my wi-fi) when it all immediately reverts to wap.voafone.co.uk etc and no matter how I overtype the correct btmobile settings, it simply reverts it back to vodafone. I was away from home an hour ago and tried to no avail. Now im home again, the settings have automatically reverted to btmobile without the need for me to do anything!!!  

What am I doing wrong?

We have a number of company iPhones, we changed our service provider to BT Bussiness, we have been issued with the BT sim, we found that we had to change the VPN from Vodafone to btmobile which is fine BUT they all (13 in total, 4's & 5's) consistently revert back to the Vodafone settings. I suspect that BT need to issue new sim's with the btmobile VPN setting written to the sim.........unless anyone has an alternative that works??
