Short answer: no. When manually installing a 4S eSIM on iPhone, enter only the SM-DP+ Address and Activation Code. Leave the Confirmation Code field blank unless 4S support specifically tells you otherwise.
Entering the wrong value in the Confirmation Code field can cause the installation to fail or show an invalid code error.
Recommended method
We recommend using One-Click Install from your 4S account, service page, or the order email sent from hi@4s.net with the subject Start enjoying your eSIM powered by 4S.. One-Click Install helps avoid copying the wrong manual details.
If you install manually on iPhone
- Open Settings > Cellular or Mobile Service.
- Tap Add eSIM.
- Choose QR code installation, then choose manual entry if your iPhone offers it.
- Enter the SM-DP+ Address exactly as shown on your 4S eSIM page.
- Enter the Activation Code exactly as shown on your 4S eSIM page.
- Leave Confirmation Code blank.
- Continue and follow the iPhone prompts.
If installation already failed
- Do not keep retrying with guessed values.
- Check whether the eSIM was already added in your iPhone SIM/eSIM list.
- If possible, go back to your 4S eSIM page and use One-Click Install instead.
- If you must install manually, copy the SM-DP+ Address and Activation Code again and leave Confirmation Code blank.

Contact 4S support through support@4s.net, a Zendesk support ticket, or Zendesk live chat. Include your order email, ICCID if available, phone model, and screenshots of the error. Do not reply to hi@4s.net; it is an automatic order and installation email sender.
