The example of wireless/GSM roaming distinguishes the following scenarios (see GSM Association Permanent Reference Document AA.39): several airlines in the United States and India have removed these fees in their national price plans. All major airlines now offer pricing plans that allow consumers to purchase roaming-free minutes nationally. However, airlines define „at the federal level” in different ways. For example, some airlines define „at the federal level” as anywhere in the United States, while others define it as anywhere in the airline`s network.  Network elements that belong to the same operator but are in different areas (typical location where local licensing is common) depend on the switch and its position. Therefore, software changes and greater processing capacity are needed, but beyond that, this situation could introduce the fairly new concept of roaming on a msc basis rather than by operator. But it`s actually a burden, so it`s avoided.  On 11 June 2013, the European Commission voted for the first time to abolish roaming charges for mobile communications.  In Russia, even domestic operators charge different rates depending on whether users are inside or outside their „region of origin”. A number of legislative attempts to eliminate internal roaming have failed due to opposition from operators.
 After the annexation of Crimea in 2014, Russian operators were criticized for not directly offering their services inside Crimea, although they were formally recognized as a regular federal issue within Russia.  The aim of the document is to establish a fair and non-discriminatory conditions for national roaming and mobile operators and to develop recommendations to the Communications Committee that could lead to the adoption of new regulations. Technically, roaming refers to a mobile phone customer`s ability to automatically make and receive voice calls, send and receive data, or access other services, including home data services, when travelling outside of the geographic coverage of the home network using a visited network. For example, if a subscriber travelled beyond the reach of their mobile phone company, their phone would automatically switch to another telephone company, if available. In the European Union, the roaming tariff regulation began on 30 June 2007, forcing service providers to reduce their roaming charges across the 28-person block. Subsequently, EEA Member States were also included. The regulation set a ceiling of 0.39 euros (0.49 euros in 2007, €0.46 in 2008, €0.43 per minute in 2009) per minute for outgoing calls and €0.15 (€0.24 in 2007, €0.22 in 2008, €0.19 in 2009) per minute for tax-free incoming calls.  After finding that market conditions did not justify lifting the restriction on homelessness within the EEA, the Commission replaced the law in 2012. Under the 2012 Regulation, retail roaming cap charges expired in 2017 and wholesale prices expire in 2022.
In mid-2009, a ceiling of 0.11 euros (HT) for sms messages was also included in this regulation.
