I'm running 24.04-1.3 on a Fairphone 5 and my provider is 50+ in the Netherlands, which uses the Vodafone network. I was recently abroad and noticed different roaming performance. I checked the APN settings, which are according instructions provided by 50+. I've set the active APN used for 'Internet', changing it to 'LTE' did not solve the issue. Currently roaming performance on my is as follows.
Netherlands: OK, mostly 5G
Belgium: OK, mostly using Proximus and 5G connection
France: NOK, mostly using SFR. Only data connection for ~first minute or so after network connection, than no more data connection. Network connection is fine. Issue present from Belgian border to Paris, i.e. not on a single spot where bad connection could play a role
(Nassau/Bahamas): Didn't use data roaming, but noticed network connection was intermittent, while an Iphone (also on 50+) had stable network connection.
Are there other users with similar experience and is a solution available?
