No data/5g connection when making calls.

[li0171]

S24 Ultra has no data/5G connection when making calls. It happens only when making or receiving phone calls and has been happening since day one. Has anyone else had a similar issue?

Yes when I was with the wrong network (ID Mobile).

Sometime networks perform worse indoors than outdoors.

Contact your network provider and share your experiences to see if a solution can be found via this channel.

Hope you find your solution

Its your network not your phone look fof yhr best network in your area wiyh a coverage checker

I am certain it is unrelated to the service provider.

1. The phone reconnects to the data network immediately after hanging up calls.

2. I never had similar issues with my old S22 Ultra.

If I make or receive a phone call, my data connection goes down completely—no navigation, email, social media, or any data at all. Everything returns to normal immediately after hanging up phone calls.

@li0171: It is potentially network related, as some networks do not support the ability to simultaneously connect to calls and mobile data. If you head to Settings > Connections > Mobile networks > 4G calling, and toggle this option off, do you notice an improvement? Also, in SIM manager, are calls and Mobile data assigned to the same SIM?

Hey Andrew, on my S20FE - wasn't an issue. Used Smart switch to upgrade to the S23+ and the No Data access on calls started. Again Smart Switched to upgrade to the S24+ and same issue. No Data/Internet when on a phone call. S24+ currently has 2 sims in use. 1 personal 1 work. Calls are made on my personal while Data is the work sim. I have checked the Mobile Network settings as you suggested and all are 5/4/3g auto network connect. No other option. What else do you suggest?

[AndrewL]

@Tarnz: If you have your calls assigned to SIM1, and mobile data assigned to SIM2, then SIM2 may be temporarily disabled while you are on a call. With this in mind, as a troubleshooting step, please try heading to Settings > Connections > SIM manager > Preferred SIMs, and assign Mobile data to your personal SIM to see if this helps.
