you want instant activation
you hate SIM swapping

Pick Physical SIM if:

you swap devices often
you want a removable backup

SpeedTalk Mobile eSIM Frequently Asked Questions

What is an eSIM?

An eSIM (embedded SIM) is a built-in digital SIM card inside your phone that allows you to activate a cellular plan without inserting a physical SIM card. Instead of swapping plastic SIM cards, you download an eSIM profile directly to your device.

Many newer smartphones support prepaid and no-contract eSIM plans, making activation faster and more flexible.

How does an eSIM work?

An eSIM works by downloading a secure digital SIM profile to your device’s embedded chip (eUICC). Once installed, the eSIM connects to your carrier’s network for calls, text, and data, just like a physical SIM card. Instant activation eSIM plans automatically push the activation profile to your phone.

What is the difference between an eSIM and a physical SIM?

The main difference is that an eSIM is built into your phone, while a physical SIM is removable.

eSIM: Digital, no shipping required, faster setup
Physical SIM: Removable card that can be moved between phones

For users seeking instant activation and convenience, eSIM offers a simplified setup process.

How do I know if my phone supports eSIM?

To use an eSIM, your device must be compatible with eSIM technology. Most newer iPhones and Android devices, including Apple iOS, Pixel, and Samsung Galaxy models, support eSIM. Your phone must also be unlocked to activate a prepaid eSIM plan.

Does my phone need to be unlocked for eSIM activation?

Yes. Your phone must be unlocked to activate an eSIM plan. Locked devices may block activation.

How do I activate an eSIM on my iPhone?

Ensure Wi-Fi is enabled throughout the entire process.
Once activation is complete, you will receive a confirmation email and a pop-up notification on your device to add the eSIM.
A banner will appear stating, “Your eSIM is ready to be installed.”
Tap the “Add eSIM” option.
Follow any additional on-screen prompts.

What is QR code eSIM activation?

QR code activation allows you to scan a code provided by your carrier. The QR code contains the activation credentials required to securely download your eSIM profile.

How long does eSIM activation take?

Most instant activation eSIM plans are completed within minutes. Activation time depends on device compatibility and network connection.

Can I transfer an eSIM to a new phone?

Yes. Many devices allow you to transfer an eSIM to a new phone, especially between newer iPhone models. In some cases, you may need a new activation code.

What happens if I delete my eSIM?

If you delete your eSIM, the cellular profile is removed from your device. To restore service, you may need to request a new activation code and complete the activation process again.

Can I reinstall an eSIM after deleting it?

Once an eSIM profile is deleted from your device, it cannot be reinstalled. A new eSIM is required. In this case, contact Customer Service for assistance.

Why won’t my eSIM activate?

Common reasons include:

The phone is locked
Weak Wi-Fi connection
Incorrect activation code
Outdated software

If activation fails, restart your device and retry the activation process.

My eSIM is installed but I have no service. What should I check?

Ensure the eSIM line is turned on
Confirm it is selected for cellular data
Check APN settings (if required)
Restart your phone

Most prepaid eSIM plans work automatically without manual network settings.

Can I use an eSIM as a backup line?

Yes. Many users choose to use an eSIM as a backup line for emergencies, travel, or business purposes. Dual SIM functionality makes this possible.

Can I activate an eSIM the same day I buy it?

Yes. With instant activation eSIM plans, you can purchase and activate service within minutes.

Can I keep my phone number with a prepaid eSIM plan?

In most cases, yes. Number porting is typically supported when switching to a prepaid eSIM plan, although processing times may vary.

Is eSIM safer than a physical SIM?

An eSIM cannot be physically removed, which reduces the risk of theft or SIM swapping. Digital SIM profiles are securely downloaded and encrypted during installation.

Can an eSIM be cloned?

eSIM profiles are protected by secure carrier provisioning systems and encryption. Unlike removable SIM cards, they cannot be physically duplicated.

Does eSIM affect call quality or data speed?

No. Call quality and data speed depend on the network and plan, not whether you use an eSIM or a physical SIM.

A pay as you go phone plan is a type of cell phone plan where you load money onto the phone ahead of time and then use it as you go. The benefits of this type of plan are that you can control your spending, since you can only use the money that you have loaded onto the phone, and it can be a cheaper option than a traditional cell phone plan. The best pay as you go phone plans will vary depending on your needs, but some of the things to look for include low monthly fees, a variety of features, and good customer service.
