==PLMN services==

A PLMN typically offers the following services to a mobile subscriber:

* Emergency calls to local Fire/Ambulance/Police stations.
* Voice calls to/from any PLMN ("cellular network") or [[PSTN]] ("[[landline]]"/[[Voice over IP|VoIP]]).
* [[Short message service]] (SMS) services to/from any PLMN or [[Session Initiation Protocol|SIP]] service (the original form of [[texting]] on a mobile phone, now often replaced by [[Messaging apps]]).
* [[Multimedia Messaging Service]] (MMS) services to/from any PLMN or SIP service.
* [[Unstructured Supplementary Service Data]] (USSD) for operator specific interactions (e.g. dialing "*#100#" to indicate the current balance).
* Internet data connectivity for arbitrary services, e.g. via [[General Packet Radio Service|GPRS]] in [[GSM]], [[IuPS]] in [[UMTS]], or [[LTE (telecommunication)|LTE]].

The availability, quality and bandwidth of these services strongly depends on the particular technology used to implement a PLMN.
