Call Cuba from the US: what works and what does not in 2026. Dialling guide with +53, ETECSA monopoly, Nauta calling, and cheapest options that actually connect.

Calling Cuba: It Is Complicated

Calling Cuba from the US is not like calling any other country. Decades of economic sanctions, a government telecom monopoly, and limited internet infrastructure make Cuba one of the most challenging international calling destinations. But it is not impossible — and it has gotten easier in recent years.

Cuba uses the country code +53. Here is everything you need to know to actually get a call through.

How to Dial Cuba From the US

Dialling Format

From a US phone: 011 + 53 + area code + local number

From a mobile with + dialling: +53 + area code + local number

Cuba does not use a leading 0 for domestic calls like many other countries. Dial the area code as-is after +53.

Example Calls

Cuban Area Codes

Cuban mobile numbers start with 5 and are 8 digits total (53 5 XXX XXXX from the US). All mobile service is provided by ETECSA, the government telecom monopoly.

What You Need to Know About ETECSA

ETECSA (Empresa de Telecomunicaciones de Cuba) is the only telecom provider in Cuba. This affects everything about calling Cuba:

Mobile data is expensive for Cubans. Many Cubans have smartphones but limited data plans. They may not always have an active data connection for WhatsApp or VoIP calls.

WiFi hotspots. Cubans often connect to internet at public WiFi hotspots (parks, hotels) using prepaid Nauta cards. If someone is online, they may be at a hotspot — not at home.

Home internet is expanding but slow. ETECSA began rolling out home internet in 2023, but speeds are limited and not available everywhere.

3G/4G mobile data is available but costly relative to Cuban salaries. A 1GB data plan costs roughly $1 USD — significant when the average monthly salary is $20-30 USD.

Cost Comparison

Google Voice does not support calls to Cuba due to US sanctions regulations. Skype charges over $0.50/min. BubblyPhone at $0.01/min is 50x cheaper than Skype for Cuba calls.

The Sanctions Factor

US economic sanctions against Cuba have historically complicated telecommunications. Here is the current situation:

Calling Cuba is legal. There are no restrictions on Americans making phone calls to Cuba.

Money transfers for telecom top-ups are allowed. You can send mobile credit to Cuban phones through services like Ding or MobileRecharge.

Some services restrict Cuba. Google Voice, for example, does not support Cuba calls. This is a company policy related to sanctions compliance, not a legal requirement.

VoIP works. There is no US law preventing VoIP calls to Cuba. The limitations are on the Cuban side (internet access and speed).

Best Time to Call Cuba

Cuba is on Cuba Standard Time (CST, UTC-5), same as US Eastern Standard Time. Cuba observes daylight saving time, but on a different schedule than the US.

Usually same as ET: 9 AM in New York = 9 AM in Havana (most of the year)

Occasionally 1 hour off: During the transition weeks when US and Cuba DST schedules differ

Best calling window: Evenings 7-10 PM Cuba time, when people are home and WiFi hotspot crowds have thinned

Practical Tips

Send mobile credit. One of the most appreciated things you can do is top up your Cuban contact's phone. Services like Ding, MobileRecharge, and Fonoma let you send credit to ETECSA numbers from the US. This gives them minutes and data.

Coordinate via WhatsApp first. Many Cubans check WhatsApp when they have internet access. Send a message saying when you will call, so they can make sure to be connected.

Patience is required. Calls may not connect on the first try. Network congestion is real, especially in the evenings. Try again if you get a busy signal or dropped call.

IMO app. Some Cubans use the IMO messaging app alongside WhatsApp. If WhatsApp quality is poor, IMO sometimes works better on slow connections.

Landlines still matter. Unlike most countries, Cuban landlines are still widely used because they are cheaper than mobile calls domestically. If calling an older relative, they may prefer to receive calls on their landline.

Summary

To call Cuba from the US, dial 011 + 53 + area code + number. BubblyPhone offers $0.01/min — a fraction of Skype's $0.53/min, and Google Voice does not support Cuba at all. Cuba shares the ET time zone. The biggest challenge is not the calling itself but whether the person you are calling has a reliable connection. Send mobile credit and coordinate timing via WhatsApp for the best results.
