I am experiencing a perplexing issue with my ZTE MiFi MU5001 device and a 3 SIM card, and I'm hoping to gather some advice and suggestions on how to address the problem.
My MiFi (ZTE MU5001) device is being used in bridge / modem mode to provide an internet connection to my ASUS home router. It was working well and was connecting to the n78 5G network band using my 3 SIM card for several months without any issues, that is, until recent mast upgrades in my area took place over the past 3 days. Since the upgrades, which involved the engineers physically replacing the 5G antennas on my mast, the device will only connect to 4G when using the 3 SIM card, even though the same SIM card still works with 5G when used in my phone. I have tested multiple 3 SIM cards with the same result.
Further troubleshooting steps taken:
Are there any potential explanations for this issue that I might not have considered, especially related to the recent mast upgrades?
Are there any additional troubleshooting steps or workarounds that you can recommend for getting the MiFi device to connect to 3's 5G network again?
Has anyone else experienced similar issues with their MiFi devices and 3 SIM cards, and if so, how did you resolve the problem?
Any guidance or insights that you can provide would be greatly appreciated.
I've attached screenshots of the network status from before and after the mast upgrades. You can see that it's now using multiple 4G bands, but the 5G will not connect, despite it indicating a 5G connection at the top of the page. The speediest results also indicate that 5G is not connecting on the MiFi, but using the same SIM in my mobile phone connects to the 5G instantly and has a full speed connection.
Thank you in advance for your help and suggestions!

Further troubleshooting steps taken:
- I tested an EE SIM card with the MiFi device, and it successfully connected to the 5G network, indicating that the device is still capable of connecting to 5G.
- I have checked the device settings, ensured the correct APN configuration (tried both 3internet and three.co.uk), adjusted the band settings i.e. locking to B3 only (as I thought it could be a CA combo issue).
- I performed a factory reset on the MiFi device, but the issue persisted.
- I contacted 3's customer support, and they confirmed that there are no restrictions for connecting to 5G on a MiFi device using their SIM card, suggesting that the issue might be related to the device itself.
