Features of the eSIM to travel to San Francisco

If you want to know more about eSIM cards to connect to the internet during your international trips, we have compiled for you a list of the most important features of these products. This way you’ll have a much more complete picture of what this product can offer you during your trip to San Francisco:

  • In most cases, eSIMs with international data only allow you to connect to the internet. Therefore, services such as voice calls are not available, so we recommend that you use apps such as WhatsApp, Messenger, or Skype. However, remember that these types of apps consume a lot of data when making a call.
  • eSIMs can only be installed once on your smartphone after purchase. Therefore, avoid at all costs uninstalling your eSIM without first contacting your provider, in case you have an issue.
  • By installing your eSIM on your Android or iOS smartphone, it will become fully dual SIM, allowing you to use both your eSIM for San Francisco and your traditional SIM card.
  • Even though you can have multiple data plans on your iPhone, you can only use one at a time.
  • Some eSIMs give you additional benefits, such as Holafly’s eSIM for San Francisco, which allows you to share data and have unlimited data during your trip.
  • Being a virtual product, the shipping costs and the waiting time doesn’t exist.
  • You will need a second screen to project the QR code and then scan it with your cellphone.

eSIM mobile coverage

As we mentioned before, one of the most important aspects that you have to look at when buying your eSIM is not the data or the days of validity that this eSIM offers you, but the coverage that you’ll have when you arrive at your destination. This is important because if your coverage is poor, the experience you will have during your trip can be greatly affected by minor problems such as latency when using apps that connect to the internet or when watching a video. However, you can also have more serious problems such as losing the internet in some areas of San Francisco.

To prevent this from happening to you during your trip, what you should do is find out what roaming agreements your eSIM provider has with the local operators in San Francisco. That is, to which cellular network will you connect when you arrive in this city? You can verify this on the official website of your provider or by consulting directly with your operator.

Your coverage will be good as long as your eSIM connects to the best cellular networks in the United States. For example, the Holafly eSIM for San Francisco connects to the AT&T’s cellular network, which is one of the best in the USA. Among other cellular operators in the United States with excellent quality, we can find Verizon and T-Mobile.
