Volvo V70 - Integral Telephone - Onbeulahheight
Our V70 is a 2005 D5 which came with a telephone and On Call and SOS comms
installation. At 83000 miles the telephone stopped working. I replaced the
external SIM as the dashboard messaging system said the SIM had failed with no
effect. The local Volvo dealer charged me for reading the codes which, they
said, said the SIM had failed. I took the car to the dealer from where it had
been bought, some 170 miles away, and he said after examination that it was the
internal SIM, ie the SIM that deals with On Call and SOS, that had failed and
was not a dealer-serviceable part. I emailed Volvo Sweden who directed me to
Volvo UK asking why it could not be serviced or exchanged for a refurbished part
as it didn't seem terribly "green" to just replace the telephone module. No
beneficial response and no help from the original dealer with a request for a
contribution from Volvo. We are informed the cost to replace is £1600, locally,
or £1200 plus software plus installation (?£1400) at the original dealership.

I cannot understand why it is not possible to just replace the internal SIM.
The telephone model is a Nokia 3210, not very complex in design. I'm informed
by a Volvo mechanic that the problem may well be just a dry joint on the PCB
which a competent technician should pick up and re-solder. Or perhaps we just
have an old-fashioned notion of repairing and maintaining kit. Has anybody any
further suggestions, please?
