povo's LAWSON coupon chance only works when the friend code, calls + data plan, and SIM activation all line up.

First, know who the coupon is for

This campaign is useful, but the value sits on the referrer side. The person issuing the code can target the extra LAWSON coupon; the person joining povo mainly needs to enter the code correctly and complete the right plan activation.

• Good fit: an existing povo calls + data user introducing a resident friend who actually needs a Japanese phone-number line.
• Possible fit for the new applicant: a student, worker, or long-stay user who already decided that povo calls + data fits better than a visitor data eSIM.
• Weak fit: short-stay visitors who only need maps, translation, hotel apps, messaging, and web. Start with the povo Japan SIM visitor guide or data-only eSIM guide instead.

The official conditions are narrow

The live campaign page makes this a calls + data referral path, not a general povo discount. The friend must use the referral code, newly register for povo calls + data, and activate the SIM card or eSIM during the campaign period.

• The campaign page says au, UQ mobile, povo1.0, and other-carrier changes are included when they move into povo 2.0 calls + data.
• If the friend joins povo's data-only plan, the campaign page says that signup is outside the campaign target.
• The official campaign list and detail page both show the June 1 to June 30, 2026 window, so do not leave SIM delivery or eSIM activation until the final hours.

Do not mix this up with visitor data products

The LAWSON wording can sound close to visitor products because povo Japan SIM also has LAWSON touchpoints. They are different decisions. This referral campaign is about povo 2.0 calls + data activation, while visitor data products are built for quick internet access without a normal phone-number contract.

• povo's own flow separates calls + data from data-only, and the data-only route is eSIM-only, new-number only, and not an MNP path.
• If you need banking, housing, school, work, delivery, or 2FA, compare normal phone-number plans on the plans page before choosing a code route.
• If you only need data before or during a trip, the coupon should not pull you into a resident-style application path.

Activation and email details can decide the result

The risk is not just entering the wrong code. The page also ties the benefit to SIM activation timing, the referrer's send count, a valid registered email address, and later delivery of the digital coupon.

• povo says SIM activation is possible from 9:30 to 20:00, and that activation after 20:00 can process differently depending on the application details.
• The coupon URL is scheduled to be sent around the end of the month after the friend activates the SIM, to the email address registered with povo2.0.
• The LAWSON coupon is valid through the end of the month after it is sent, cannot be used in some LAWSON-related stores or smartphone checkout, and the extra coupon benefit is capped at 10 sends per referral code.

A safer order before using the code

Treat the referral as a final layer after the plan decision. That keeps a small coupon from hiding the bigger setup checks: phone-number need, identity, device, payment, Wi-Fi, and activation timing.

• First, decide whether the new user needs calls + data or a visitor data eSIM. Data-only cannot solve normal carrier SMS or phone-number tasks.
• Second, confirm device compatibility, SIM card vs eSIM, Wi-Fi for setup, identity/payment readiness, and whether the friend can activate by 2026-06-30.
• Finally, reopen the official campaign page on the day the code is used. Use the FAQ, plans page, and referral page only after the current official terms still fit.
