How To
Unlock Tesco Internet Phone Siemans DP450
Unlock your Tesco DP450 IP Phone to use this with other VoIP providers.
Gigaset Communications have created a process that enables Tesco
Internet Phone subscribers with Siemens Dual-Phone DP450 to unlock the
phone from the Tesco Internet Phone service. This will enable the phone
to be used with other Internet Telephone services. This follows the
recent news that the Tesco Internet Phone service is to be ceased from
April 26th, 2010.
This is an approved method for unlocking the Siemens Dual-Phone DP450
defined and released by Gigaset Communications, the original supplier of
the phone to Tesco.
If this procedure is not followed exactly your phone might not
work anymore. In this case Gigaset Communications cannot
accept any warranty claims.
