Ya I encounter this before when I go japan on my ip7 but my mum on 6+ no issue and previous I on ip6 no issue too
Did u try network lock ?
I can only suspect it's iphone switch to intel and not Qualcomm which got issue with network tx Rx strength
I suspect the next iphone 8 won't use Qualcomm as apple going intel fully
Lan lan just use a mifi when u go overseas and use Whatsppls for calls lor
But local use I have no issue with network suspect it's network firmware
Unless u take up oversees mifi or oversees data sim
And if must sg sim for voice and Sms call u need to manual set to the telco which helps little but I try this method before it will still goes out of service but will recover in a while
I suspect why our local telco no issue is we rvon their network so the telco carrier firmware is updated to align with it iphone 7 intel weakness so if only we can update the overseas telco u roam to telco firmware carrier it might help this is my own theory
For me I manual force to lock onto SoftBank when I go japan it's help but it's not 100% but luck I got a overseas mifi for my data needs
Hope the next gen of intel cellular chip for iphone 8 will improve
Hi guys anyone experience oversea no service from network telcom ? I had this issue when I was using iPhone 7 plus last time when it launch.
Then recently I swap over to iPhone 7 red and had the same issue. I have 2 sim card (singtel and starhub) while oversea both will random change telcom and sometimes will display "no service" for like 1-2 minute before they reconnect. I never had this issue in my Android dual SIM phone .
I call both service provider and request for a backend network reset and the same problem persist. Anyone can enlighten me ?
