Freddy Muñoz could not reach his daughter, but continues to smile.
The 61-year-old Honduran used one of the telephones made available by the Red Cross caravan migrants to allow them to call their loved ones home.
"I do not like phones, I do not know how to call," he told AFP.
Muñoz tried several times to join the United States. His only daughter, now an adult, asks him every time to interrupt his "adventures".
"Tell me: stop that dad", he says after leaving the tent in front of which dozens of migrants are siding.
In the field located in a stadium in Mexico, about 5,500 migrants took place from Sunday on the road to the United States. They benefit from all types of services created by the Mexican authorities: clothing and food distribution, children's play labs, hairdressers, doctors, dentists, ophthalmologists, psychological support and even a mariachi orchestra to brighten up their stay in Mexico. .
But being able to make a phone call to relatives remains one of the most requested services for these migrants who left San Pedro Sula on October 13, fleeing poverty and violence in Honduras.
Alvaro Rodriguez, 18, left his country after the murder of his father by a criminal gang. "I would like to go to Tijuana (in northern Mexico) to work there, because going back to the United States will be difficult" he confides, having managed to speak a few minutes to his relatives.
"Before we leave, let's say to our families:" Wait for our call ", says Norvin Alvarado, a 22-year-old Honduran migrant.
Some of these conversations end in tears, others in a bright smile.
For those who own a mobile phone, it is essential to recharge. Electrical sockets have been installed in different parts of the camp.
On the road, "it is rare that we offer you a call," explains Belkis Salinas, a Honduran who waits for his cell phone to be recharged by talking to other migrants.
Some prefer to leave this huge field to look for an internet café in the neighborhood, even if the price of the connection, 14 pesos for an hour ($ 0.71), is often too high for them.
"I'm just looking for an Internet connection to tell my family where I'm going and what conditions are," says 19-year-old German Guatemalan Navarro.
The migrants in the caravan should then continue the journey to the border between the United States and Mexico.
Two other caravans currently cross southern Mexico and could reach the Mexican capital in the coming days.
