Phone problems

I apologise if anyone’s been having difficulty getting through lately on 087 2396281.
I have been having frequent incidences of signal loss recently which I was blaming on vodafone and/or my phone.
Today I couldn’t get a signal at all and it turns out that the problem was that my
sim card was faulty and finally failed completely today.
The lady in the vodafone shop said that it’s recommended to get a new one every year.
Mine was about 10 years old.
Anyway everything seems OK now with the new sim.
