On my S10 E/OS, I can’t make calls but I can send text messages, and when I use an app like WhatsApp to make a call, I sometimes can’t hear the other person. Can anyone help?
Sounds like the usual “lack of VoLTE” problem.

Most countries are deactivating their 2G and 3G network.
All Samsung phones, including yours, do not allow /e/OS to have 4G/LTE network connection.
Therefore it is highly likely that your phone is obsolete when used with a custom ROM that do not have access to the 4G/LTE drivers/firmwares.
Messenger calls should work. Audio routing issues can come up if you use headsets / bluetooth maybe.
You can install a micrphone test app to check if there’s a fundamental hardware issue though.
while this is true as of now, some of the efforts to bring an IMS stack to individual Samsung models bear fruit.
The phh/ims derived package used for bringing it to the S9 is more portable than other methods. It’s experimental and will probably first find a unofficial build per Samsung model each - but it’s a silver lining for them to continue to use the hardware.

That’s possible because the mobile internet provider I use is new in our country and they don’t have any 3G or 2G masts.
On 4G, for example, I can install apps, watch videos or use a browser, but when I make calls over the internet – such as on WhatsApp – I can hear the other person for a moment and then the sound cuts out. I have to end the call and call them again.
My father had an S9 and an S10e running /e/ OS both of which suddenly suffered from similar network problems from one point in time, even before the official deactivation of the 2G-3G networks from the provider. Some network protocols or frequencies were probably deactivated without notice.
As we all need a dependable smartphone to get the benefits they bring, what matters most is to keep a device on an official /e/ OS version that is well maintained (that gets firmware updates for things like network antenna, microphones drivers, screen sensor setting) and receives Android-major-version-automatic-upgrades (OTA = user-friendly update from the normal OS interface and not from the low-level recovery system that erases every data and setup) ideally with a locked bootloader to maximise app compatibility.
The only phone brands that have been sold continually on Murena shop are Fairphone and Teracube.
Fairphones are expensive and too big, yet they are a good trade-off to avoid having to buy regularly a new device of another cheaper type because of the time it takes for Murena to update those cheaper models to the latest Android version (/e/ system upgrades happen in practice less than once a year on all phones other than Fairphones, because it is hard for Murena to maintain all those models and to keep up with the pace of android versions).
The other option is Teracube, they are cheaper and slightly smaller than Fairphones. They are not upgraded to the latest Android version as often as Fairphones but as they are much cheaper, so they might be as good of a compromise.
Therefore I was forced to replace the smartphone of my father by one of these two options above to have ensured app compatibility for several years without needing manual software upgrades/updates.
