Lack of 4G in Italy

[Moelder]

On a trip to Milan last week my daughter, who is also an O2 customer, had 4G but I did not. I have a lower data allowance to her so was this the cause of my lack of 4G? We were also on different networks during our stay.

It would depend on the network you were connected to.
You could have done a manual network search to get the same one as your Daughter had.

I tried to manually select the same network as my daughter but it was not listed in my available options.

Roaming networks are programmed into the sim so there's no reason for any differences unless your sim is so old as to not be updated with the latest networks or agreements.
Also PAYG and contracts would see differences.

@Moelder Also does you phone support 4G?  What phone is it, is it updated to latest software.

Android phones especially if there running on older software or not updated will not always see the networks as 4G abroad. 

I had had a Samsung that knew three had 4G but refused to connect, I updated the software 2 days later and it connected fine.

also as mentioned older sims can cause the same issue as well.

I have an iphone 6S which I keep updared and have a 5GB 4G allowance

Updated not updared.

Iphone can def see all networks and he status of them abroad,  the sim must be a older one then and mentioned.

if you just go into an o2 shop and advise them ur having issues with the sim. They will replace it for you. Or u can call customer services to send a replacement out the follow the instructions to transfer it over.

the sims are pre programmed with networks for using overseas.  So some networks are given priority over the others.

When you searched did you see those networks mentioned below,

iphone doesn’t show the networks quickly so you may have to wait a couple of mins then choose one

There are four network providers currently operating in Italy, with one merger and one new entrant scheduled:

• TIM.
• Vodafone.
• Wind merging with Tre to WindTre.
• 3 (= 'Tre') merging with Wind to WindTre.
• [Iliad - expected to start in summer 2018]

Thank you so much. That is most likely my problem as my sim is 4 and a half years old. I will do as you advise.

TIM was not listed when I searched but my daughter was automatically connected to TIM when she turned her phone on at the airport after we landed
