Orange roaming for PAYG appears to be going backwards.
PAYG roaming in Singapore no longer works. Orange customer service are
unaware of the problem and their final solution was to move to another
network (Voda PAYG works just fine on all 3 Singapore networks). A
year ago the same SIMs in the same phones worked fine.
I am familiar with roaming techniques (e.g. manual selection of
network, making sure the phones can operate on the correct band, and
checking that there is good coverage) and I am confident it is not a
problem in any of these areas.
Have Orange withdrawn PAYG roaming from other countries too?
Spent some time on phone to customer service - one of their
suggestions was to remove SIM and battery, wait 15 minutes and try
again. Not sure what this was supposed to achieve!
If they have decided not to support PAYG roaming then fine but they
should tell their customers. These SIMs spend over a month a year out
of UK.
