Corrections.
- Unlimited eSIMs decoded and the best eSIMs for adventure travel: Airalo's speed after its 3 GB daily cap is 1 Mbps, per its fair-use policy; we'd previously said the rate wasn't given. Maya Mobile's help centre describes a 10 Mbps throttle after 3 GB a day, which we'd missed; we'd previously said Maya published no threshold.
- Reviews and comparisons, after a pre-publication fact check against providers' own pages: Nomad's unlimited passes are non-refundable (its refund page excludes "all Unlimited plans"), which our Nomad pages hadn't said. Airalo's Nepal page does have a 15-day pass ($79); two 7-day passes ($70) are still the cheaper way to cover two weeks. Airalo's "3GB per day at 20 Mbps" wording comes from its unlimited-plans FAQ, not its country pages. Holafly's $3.50 admin fee can apply to full or partial refunds depending on data used, not only partial ones. Lotso Travel's terms give "e.g., 14 days" as an example refund window; we'd said they gave no number.
- Ubigi's network-transparency score fell from 4 to 2: only one of the five Ubigi country listings we read (Japan) names its networks. Its overall score moved from 3.8 to 3.5.
