Zero, One or Dual SIM Cards: Which is Best?

August 19, 2020

For U.S. retailers, considering whether to sell smartphones that use SIM cards or non-SIM card phones may seem like a moot point. Most U.S. phones don’t require SIM cards, and are tied directly to a specific service provider; they can’t be used on other carriers unless the user asks for the phone to be unlocked. Even then, it’s not always possible. Service providers do this on purpose. It’s their way of guaranteeing that the consumer continues to use their services. Since many offer these smartphones on payment plans or with major discounts if the user agrees to a contract, many users consider it to be a fair trade.


However, not all countries operate in the same way. Most of the world’s smartphones operate with a SIM card, which can be removed from the phone and replaced with a different card from a different provider. These unlocked phones have the ability to not just work on any carrier within a certain country – they also work in multiple countries by simply changing out a small microchip in the phone. Most of the time this is a much more reliable and cheaper alternative to extending a U.S. provider’s service abroad. 


The unlocked SIM card smartphone may not be a large seller for most U.S. consumers, but as more people travel abroad, especially for business, having a phone that can work well in any country is essential. Not only is a SIM card phone helpful in this case, a dual SIM card phone is an even better option.


The dual SIM card phone can hold more than one SIM at a time, allowing the user to easily switch from one country’s service provider to another without the hassle of removing one tiny chip and replacing it with another. According to market analysts, the dual SIM market is showing promise of huge growth by 2024. Some of the largest smartphone providers in the world are already producing dual SIM phones, including Samsung, Huawei, LG and Motorola.


Fortunately for retailers, most smartphones are available in both SIM and non SIM options; the size and specs remain the same. This means that an unlocked iPhone 7 needs the same protective case as its non-SIM version.
