I am a 3 customer since few years and I had a micro sim card on my phone that is a dual sim. I normally used the 3 sim on the 2G network without any issue.
Just recently I got a new mobile accepting nano sim card so I replaced the old one with the new.
The problem now I can not use anymore my phone on the 2G network. Normally the manual registration goes fine (I can call and receive calls) but it last few minutes. After a while the connections drops. Some time I simply can not connect to the 2G network (I get Network Registration failed).
Now I wonder if I can roll back to my previous old sim card that was just working with no issue on the 2G network. Or if there is a way to register the new nano sim card to the 2G network.
If not, I have to leave 3; I need to use it on my 2G phone.

I do not think so. The phone works perfectly on the 2G when I use the sim of the other provider.
I have been told in a local shop that 2G is not supported anymore with the new sim. I wonder if it is true and if I can swap back to the old sim (that I still have).

Yes, I think the old sim were all 2G. That is the reason they worked fine.
But can I still reuse my old 3 2G card (that I still have)?

@billbond4is right here but he may have an old O2 SIM. Can you tell me if the old SIM you have is still active?
Yes, my old Vodafone sim is still active and works just ok. The reason I can use is because I just cut the old micro sim to make a nano and use in my new phone.
