Hello @ChopraRohan ,
Welcome to the community,
EE is not responsible for network connections in other countries, that would be down to the country you are in.
Have you tried a manual search to see if you get a better connection.
I take it you have roaming enabled on your account, which you should have done whilst in the UK?
To contact EE customer service dial 150 from your mobile phone or ring customer service for free using Skype or another phone: +44 800 079 8586 or +44 800 956 6000.
