Is porting my number causing problems with E911? Wireless Local Number Portability (WLNP) allows wireless subscribers to switch providers at a given location while maintaining the same phone number. Mobile subscribers who wish to carry their phone number should contact the potential new network operator who will start the porting process by contacting the consumer`s current mobile operator. In Hungary, the portability of geographical numbers has existed since 1 January 2004. Portability of non-geographic geographic numbers (including mobile phone numbers) has been available since 1 May 2004.  A special prefix +36 21 has been added to allow the phone number to be anywhere in the world, in addition to the area code +36. In mobile communication there is the concept of recording the location for a “mobile station” (for example.B. a mobile phone) to attach to the number. When a number is selected, it is necessary to determine where the mobile station is present on the network. There must be a mechanism for such transmission. (An example of this system can be found in the article on the GSM network.) If you want to contact a new provider for a mobile phone service and keep your mobile phone number, the provider is required to do so: I heard that some consumers had trouble bearing their numbers when the wireless LNP was first introduced. What can I expect if I try to port my number now? In South Korea, the mobile phone number portability service began on 1 January 2004. One of the things that differs from other countries is that SK Telecom, the dominant operator that holds more than 50% of the market share. In order to prevent users from moving to the dominant operator, the government gave the second and third operators a period of six months and one year respectively.
As a result, only SK Telecom subscribers were able to switch to other operators in the first six months.  Japan`s Ministry of Internal Affairs and Communications (MIC) has spent three years practicing mobile phone number portability since its first working group began in November 2003. As a result, NTT DoCoMo, KDDI and Softbank accelerated the price fight, which however had a limited effect due to already competitive pricing plans and customer loyalty. Overall, the portability of mobile phone numbers in Japan has not been very successful, since the transition cost for the customer is due to the blocking of the SIM card, which has long allowed operators to establish the portability of mobile phone numbers, which has allowed operators to close subscribers with price plans, and the importance of mobile internet mail. In Hong Kong, fixed number portability has been available since 1 July 1995, the same day as the liberalisation of the fixed telephony market (i.e. the lifting of the franchise monopoly), which was a government requirement.  Mobile phone number portability has been available since March 1, 1999.  Although the government has authorised the transfer of a fixed number to a mobile operator or vice versa, the introduction of this service is decided by fixed/mobile operators on a voluntary basis. Since October 2009, fixed number portability is no longer available.  In Denmark, portability of fixed numbers and ISDN was introduced on 1 January 2001. Mobile phone number portability was introduced on 1 July 2001.
 In 2006, 238,293 fixed lines and 456,159 mobile phone lines were transported. Considering that the number of fixed lines was 2,974,000 at the end of 2006 and that the number of mobile phone lines was 5,828,000, about 7.9% of the lines were transported in 2006. In Albania, portability of mobile phone numbers was introduced on 4.05.2011 (AKEP). While for fixed numbers, it started in some geographical areas in September 2012 and was available in all countries until 01.04.2013 (AKEP). In Finland, mobile phone number portability was introduced on 25 July 2003.  The effects of mobile phone number portability in Finland are greater than in other countries. In one year (June 2003 – June 2004), the combined market share of TeliaSonera, Elisa and DNA increased from 98.7% to 87.9%.  On 29 August 2019, the Federal Institute of Telecommunications (IFT) announced that, at the request of telecommunications service providers, it would migrate its management of the portability database to Mediafon Datapro, so that portability was temporarily suspended from 30 August to 1 September.  On 2 September, portability resumed, with service now provided by Mediafon Datapro.
 In Ireland, local number portability was introduced in 2000 using an IN solution with a common routing database. . . .
