I am having problems with O2 roaming in Italy and Slovakia. I have a new Samsung S6 on an O2 refresh contract. I have had international roaming and O2 travel activated on my account for over 10 years.
The phone will connect to the international networks but seems to have problems with seamlessly changing netwroks when one network becomes out of coverage...for example when on TIM if the signal goes it will display Emergency Calls only.
I then have to manually select anither network e.g. Wind.
Even if the original network becomes available I have to manually re-select the network or restart the phone.
I thought the whole concept of roaming was just that..to seamlessly roam between networks.
I have rebooted the phone and taken out the SIM card etc.
I have tried it wity wi-fi on and wi-fi off and with data roaming on and data roaming off.
The problem isn't a local issue as it happened all over the Amalfi Coast area and then in Slovakia.
Also my wife's phone would seamlessly roam between networks while she was stood next to me while my phone displayed Emergency Calls only.
Also I noticed that several networks wouldn't work with the O2 SIM card...when manually selecting the network it would take over 2 mins to search then another 30 seconds before 'Unable to Connect-try later' was displayed.
Yet these networks have roaming agreements with O2- Vodafone Italy and Telecom SK in Slovakia.
O2 customer care insisted it would be resolved by removing the SIM card and restarting the phone but this doesn't work.
I have had the latter proble-unable to connect-try later- since moving to Samsung Android phones-first with the S2 then S4 but not the problem of not allowing seamless roaming.
Any help appreciated!
