@Bordeau 2 bars does not really mean bad reception. It is more the speed that counts
What speed are you getting? and are you connecting with 4G/LTE or 5G?
Depends on your plan, you should get around 3Mbps if you have a 3G plan, 50 to 100Mbps if you have a 4G plan or 100-250Mbps if you have a 5G plan
You can also try Reset network settings after a device reboot to see if the speed improves
