When it comes to network compatibility, the two main technologies used worldwide are GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access). GSM is the more prevalent network standard globally, used by the majority of countries. CDMA, on the other hand, is primarily used in the United States and a few other countries. It is important to consider the network standard of the country you plan to visit and ensure that your phone supports it to ensure compatibility and uninterrupted service.
LTE (Long-Term Evolution) is a standard for high-speed wireless communication for mobile devices. Different countries and regions use various LTE frequency bands, and having a phone that supports these bands is crucial for seamless connectivity. Most modern smartphones, including the ones mentioned above, are designed to support a wide range of LTE bands, ensuring compatibility with networks around the world. It is recommended to check the LTE bands used in your destination countries and choose a phone that supports those bands.
5G is the next generation of wireless technology that offers faster speeds, lower latency, and improved reliability. As 5G networks continue to roll out globally, having 5G connectivity on your phone can provide a significant advantage. The phones mentioned above, such as the iPhone 12, Samsung Galaxy S21, Google Pixel 5, OnePlus 9 Pro, and Sony Xperia 1 III, all offer 5G connectivity, allowing you to experience the benefits of 5G technology where it is available. However, it’s important to note that 5G availability may vary by country and carrier.
Dual SIM functionality allows you to use two SIM cards in a single phone, providing flexibility and convenience, especially for international travelers. There are two types of dual SIM technology: physical dual SIM and eSIM. Physical dual SIM phones have two physical SIM card slots, allowing you to use two SIM cards simultaneously. eSIM, on the other hand, is a technology that allows you to have multiple active SIM profiles on a single phone without the need for a physical SIM card. Some phones mentioned above, like the iPhone 12 and Google Pixel 5, support eSIM, while others offer physical dual SIM slots.
Dual SIM functionality offers several benefits for international travelers. Firstly, it allows you to use your home number and a local number simultaneously, ensuring you can stay connected to both your contacts back home and the contacts in the country you are visiting. This can be particularly useful to avoid expensive roaming charges. Secondly, dual SIM phones offer the freedom to switch between different networks or plans to get the best coverage and rates. However, it’s important to note that not all dual SIM phones support simultaneous active calls on both SIM cards. Some phones may require you to switch between the SIM cards for calls or data usage.
Choosing between an unlocked phone and a carrier-owned phone depends on your specific needs and preferences. Unlocked phones offer the advantage of being able to switch between different carriers and networks, giving you the flexibility to choose the best plan or coverage for your needs. Unlocked phones are not tied to any specific carrier contract, allowing you to use them with any compatible SIM card.
Carrier-owned phones, on the other hand, are typically less expensive upfront as they often come with a subsidized price when purchased with a carrier contract. These phones, however, are typically locked to a specific network, meaning they cannot be used with other carriers or networks without unlocking them.
If you choose to go with a carrier-owned phone, but still want the flexibility to use it with other carriers, you will need to go through the unlocking process. This process involves contacting your carrier and requesting the phone to be unlocked. Once unlocked, you can use the phone with any compatible SIM card. It is important to note that not all carrier-owned phones can be unlocked, so it is best to check with your carrier about their unlocking policy before making a purchase.
VoLTE (Voice over LTE) is a technology that enables high-quality voice calls over 4G and 5G networks. Compared to traditional calls over 2G or 3G networks, VoLTE offers clearer audio and faster call connection times. When traveling internationally, having VoLTE support on your phone can ensure that your calls sound crystal clear, even when making calls over data networks.
Wi-Fi calling allows you to make phone calls using a Wi-Fi network instead of a cellular network. This feature can be incredibly useful when traveling in areas with weak or no cellular coverage but have access to Wi-Fi. By enabling Wi-Fi calling on your phone, you can make and receive calls as if you were using a cellular network, without incurring additional charges or relying on a strong cell signal. Wi-Fi calling is especially beneficial for international travelers as it allows you to stay connected without incurring high roaming charges.
Different countries and regions use different frequency bands for their cellular networks. Some phones are designed to support multiple frequency bands, such as quad-band or penta-band phones. Quad-band phones support the four primary GSM frequency bands (850, 900, 1800, and 1900 MHz), offering a higher level of global compatibility. Penta-band phones, on the other hand, support five frequency bands, including the four primary GSM bands and an additional WCDMA band (2100 MHz). By choosing a phone that supports multiple bands, you can ensure that your phone will work on a wider range of networks.
LTE, GSM, and CDMA networks also operate on specific frequency bands. It is important to check the LTE, GSM, and CDMA frequencies used in your destination countries and ensure that your phone supports those frequencies. Most modern smartphones, including the ones mentioned above, are designed to support a wide range of LTE, GSM, and CDMA frequencies, providing global compatibility. However, it is always a good idea to do some research and verify the frequency bands when purchasing a phone for international use.
The Apple iPhone 12 offers excellent global compatibility, supporting both GSM and CDMA networks.

The iPhone 12 takes advantage of ultra-fast 5G connectivity, providing faster download and upload speeds when connected to a 5G network. As 5G networks continue to expand globally, having a phone that supports 5G can offer a significant advantage, enabling you to experience faster internet speeds and improved performance for streaming, gaming, and other data-intensive tasks.
The iPhone 12 supports eSIM functionality, allowing you to have multiple active SIM cards without the need for a physical SIM slot. This can be particularly useful for international travelers who want the convenience of having a local SIM card while still being able to use their home number. With eSIM, you can easily switch between multiple SIM profiles and manage them directly on your iPhone, eliminating the need to carry multiple physical SIM cards.
