Frequently Asked Questions
Do I need to dial 044 or 045 to call mobile phones in Mexico?
No. As of August 2019, Mexico eliminated the 044 and 045 prefixes. You now dial all numbers (landline and mobile) as 10 digits directly after the country code (+52).
Can I get a local Mexican number for my US business?
Yes. StartACall allows you to provision virtual numbers in cities like Tijuana or Mexico City, allowing your Mexican suppliers to call you locally while you answer in the US.
Does this work for factories with poor cell reception?
Yes. Because StartACall uses VoIP (Voice over IP), calls are routed through the internet connection. If your factory has Wi-Fi or Ethernet, you will have perfect call quality regardless of cellular coverage.
What is the Maquiladora Industry?
Maquiladoras are factories in Mexico that are largely duty-free and tariff-free. They are run by foreign companies (mostly US) to assemble products for export. Reliable telephony is crucial for their just-in-time logistics.
