The same mobile number has two written forms, and this is where Argentina trips everyone up: internationally +54 9 11 1234-5678; dialled inside Argentina, 011 15-1234-5678. The 15 is for domestic dialling and the 9 for international — the two never appear together. Use the international form (with the 9, without the 15) on sign-up forms.

Area code + subscriber number, 10 digits in total |
Mobile carrier | An Argentine national number is always 10 digits: a 2–4 digit area code (11 for Buenos Aires) plus the subscriber number. Fixed and mobile share the same area codes, so the number itself doesn't say whether it's a mobile — the difference is in how you dial it: add 15 after the area code domestically, or add 9 after +54 and drop the 15 from abroad. With porting in place since 2010, a number reveals neither the operator nor the service type. |
Physical SIMs can sign up without issues.
Mobile prefixes by carrier.
Number portability applies — a prefix only shows the original carrier.
The regime was created by Secretariat of Communications Resolution 98/2010 (amended by 67/2011), using a central database with all-call-query lookup. The current rules: only the account holder may apply, and you apply at the operator you want to move to, with its standard form and a copy of your ID; the process must not take more than 1 working day (up to 10 in complicated cases) and the service may not be down for more than 3 hours; once ported you must stay 30 days before porting again. One difference from most countries: the official page states the operator may charge up to the equivalent of 100 telephone pulses per port, so it isn't unconditionally free.
Argentina does have an official lookup: ENACOM's “Buscador de Prestadores” takes a number and shows both the original provider and the current one; if the two match, the number has never been ported. In our own testing that lookup is blocked by ENACOM's firewall from outside Argentina.
Owned by Telecom Argentina.
On 24 February 2025 Telecom Argentina bought Telefónica Móviles Argentina, but the merger still hasn't been cleared: the competition authority's ruling of 17 June 2026, based on an ENACOM technical report, requires Telecom to hand 6 million mobile customers and the matching infrastructure to a new entrant and to return 130 MHz of spectrum, or the deal will be rejected. So Personal and Movistar, while owned by the same group, still run and sell separately.
Owned by América Móvil. ENACOM's porting page lists exactly three places to apply: Claro, Movistar and Personal.
All Argentine mobile lines must be registered to their holder (ENACOM Resolution 8507/2016); foreigners must register in person with an original passport. Each prepaid top-up lasts 180 days, and a line is cancelled 60 days after the last top-up expires.
