I am not sure whether this works as I believe broadcast settings are not stored in SIM. I searched and stumbled on this HTC support page where the solution is said as:
I resolve problem. It is very simple. Just put your sim card in old or
some other phone and turn off cell broadcast info option. Then return
your sim in new phone. On my HTC Desire 500 there is no option for
cell broadcast. After this procedure I do not recives messages.
Then, another search result says with better detail (you may have to search for
Cell Broadcast. Though this not deals with your phone (with HTC Desire T327W), I guess this seems to be a common issue with few HTC phones. As per that page:
26-Sep-2013 - My earlier review talks about Cell Broadcast messages
problem faced by me while using HTC Desire XDS. After a lot of
followup with HTC, I have got the steps using which the Cell Broadcast
messages have got disabled in my Desire XDS. The steps taken by me
were as follows for each of the two SIM cards:
a) Find an old phone which has an option to enable/disable Broadcast Channels and Messages
(in my case its a Samsung D500).
b) Insert the first SIM in that old
phone and go to the settings menu for Broadcast messages.
c) At first
the Channels and Messages usually appear as disabled. I changed the
setting for both Channels and Messages to Enabled in the old phone.
d) Switch-off the old phone and Switch-on
e) Go to the settings menu
for Broadcast messages. Change the settings for both Channels and
Messages to Disabled.
f) Switch-off the old phone and Switch-on
g) Switch-off the old phone and remove SIM card
h) Do the same steps (a-g) for the second SIM
i) Insert the SIM cards back in HTC Desire
Now I do not get any Broadcast Messages, its such a relief. I hope HTC
provides a better and elegant solution via a software update in the
upgrade to Android 4.3.
