Tip: Check Manual Profile Selection while Changing Countries


Keep the CallBack option disabled

Disable Call Back option      

The CallBack option is an old phone setting, now rarely used by international travelers. It often leads to the interruption of an international sim’s phone network. This option was earlier used to initiate a call from the server via a specific number to a user instead of directly calling the number. This resulted in savings as outgoing calls were too costly. Nowadays, direct calling is used thanks to reduced roaming charges and use of better cellular technology. This makes using the Call Back option unnecessary while traveling. It would be wise to keep the Call Back option disabled and if your phone is having connectivity issues, you should also check for the same.

Tip: Disable the Call Back option if enabled


Note down the APN Setting

APN settings

The foremost thing to be done by any international traveler when they purchase an international sim is to set up the (Access Point Name) APN settings in their phone. Once set, there is no need to configure the phone and the International Sim Card works seamlessly. This is where a smart traveler does things differently. They save the APN settings separately in their smartphones in case the handset’s configuration changes while they enter a new territory.

Tip: Save the APN settings separately in your Smartphone


Learn Manual Network Selection

Strongest Signal

Most international sims automatically connect to a default local carrier network when a traveler enters any new area within a country. In most of the cases, the International Sim Card works flawlessly but there are a few regions where the default local carrier network might not be the strongest. This can lead to poor connectivity and irritate a traveler. Instead of calling the customer care service, a simple step of selecting the strongest recommended local network available from the handset can instantly resolve the problem. Thus, saving precious time and grant peace of mind to any traveler.

Tip: Select the Strongest Recommended Local Network Available Manually  


Use Correct Dialling Format

Correct Dialing Format

This is the most silly mistake made by any traveler. While roaming different travel destinations, a traveler tries calling different international phone numbers. These can include either a country’s local sim or any international sim number. Travelers often don’t use the correct country codes or dialing format when making a call. This is the most common occurrence when dialing a saved contact from the handset, as no one saves a number in an international dialing format. They often blame the sim card and reach out to customer care to solve an issue where there is none. Remembering the correct dialing format can save a traveler from mental anguish and also save precious time during travels.

Tip: Always confirm the correct dialing format before placing a call while traveling


Use the Virtual Number Service

Virtual Number Service

Most travelers are not aware of the different features available in their International SIM Card. They try to reduce receiving the calls of their friends & relatives to save them from incurring high calling costs. This can be easily avoided by using the Virtual Number Service at a nominal price. The Virtual Number Service is a smart service through which incoming calls for travelers are charged as local calls instead of being charged as international calls irrespective to the country the traveler is traveling.

This saves a lot of money for any person making the call and they can talk to the traveler to their heart’s content. The best thing about this service is it is renewable. To continue the same number, a customer just needs to repeat the order for the virtual number before the expiration of the virtual number’s current validity.

Tip: Always use the Virtual Number Service for receiving calls during travels
