It is expensive to use the services of your own company when traveling abroad. Automatically you get into the roaming zone when cellular services are also provided by the network of a foreign operator. At the same time, the prices for calls soar: you have to pay both your own and others.
For those who have a laptop or smartphone, it is enough to install the Skype program, find a place where there is free Internet access, and call all over the world for free. The main thing is that your subscriber also has such a program. And it's cheap to get in touch with regular phones.
Alternatively, you can purchase a local SIM card. This type of communication is cheap, because when you buy a tourist SIM card, you make a prepayment for minutes / sms from the cheapest foreign operator. At the same time, you do not depend on the Internet, you can keep your number, and calls will cost about 2 cents.
If you don't want to buy a SIM card and take a laptop with you, try another way to save money. When entering the country, disable automatic operator selection in the settings. And then manually connect to the overseas operator with the lowest rates. True, to find out whose services are cheaper, you must in advance in your telephone company.
An old proven method: when you arrive in a foreign country, buy a local SIM card at a kiosk or store. This is really beneficial: you pay several times less for calls to your home than if you stayed in roaming. But the new number will have to be communicated to relatives, and this is costly. In addition, a subscriber from Russia will pay for incoming calls, and this is expensive.
