Is APN dangerous?

No. It won’t damage or affect the phone or SIM. If you have issues, go back to your old APN (or another). The only thing changing APNs could effect is your ability to send/receive MMS, and data speeds (which you’re seeing the improvements already).

What is QoS in LTE?

In an LTE network, QoS parameters are defined at service level and at bearer level. SDF QoS parameters are service-level QoS parameters while EPS bearer QoS parameters are bearer-level QoS parameters. Service level and bearer level are also called as SDF level and SDF aggregate level.

What is APN bearer?

Bearer. The Bearer setting allows you to restrict the current APN configuration to only be available when specific communication protocols are in use. … It allows you, for example, to use one APN configuration to be selected when LTE is in use, and another APN configuration to be selected if eHRPD or EvDO is in use.
