It is free. Globe states that its online SIM registration is zero-rated, so you pay no charge to complete it, and the law behind it, the SIM Registration Act (RA 11934), requires telcos to run the program at no cost to users. If anyone asks for money to finish TM SIM registration, treat that as a red flag and walk away, because no official step in the process carries a price tag.
Free does not mean nothing ever costs money, and a few nearby expenses cause the confusion. A new TM SIM pack has a price, tied to the starter load or promo inside it. Getting to a Globe Store may cost fare. Some people also pay a neighborhood shop or a stranger online to register for them, but that fee is a service charge for convenience, not a government or telco fee. Paying it also hands your ID photo and selfie to a third party, which is the part that worries me most about paid TM SIM registration.
Scammers lean on that confusion around TM SIM registration. Fake pages advertise a processing fee, an activation fee, or a paid priority queue, and some ask for payment through e-wallets. Official channels stay limited to Globe’s registration portal, the GlobeOne app, and Globe stores. No legitimate step requires payment, and none requires your OTP anywhere except the registration page itself.
Data use is the other small question. Because the official portal is zero-rated, you should not need load to reach it, though you still need a working connection to open the page and upload your ID and selfie. A weak signal costs time rather than pesos, so retrying with better reception or at an off-peak hour beats paying a helper. If you cannot upload at all, TM SIM registration at a Globe Store is another route, and the staff can confirm there is no charge.
The genuinely expensive choice is skipping registration. A SIM that is not registered can be deactivated, and during the 2023 deadline Globe warned that unregistered numbers would lose their services and load balances. Its help page also says a deactivated SIM cannot simply be repurchased with the same number. Compared with that, an hour spent on the free portal, with a clear ID and a steady connection, is the bargain. If you are helping a relative who is not comfortable online, sit with them at home rather than handing their phone and documents to a stranger. Free TM SIM registration only stays free when you do it through the channels Globe itself publishes and keeps current.
For a plain walkthrough that stays on the free official path, the TM SIM registration guide is a reasonable reference to keep nearby, with the checklist, ID photo rules, and status-check options all in one place. Policies and promos change, and your situation may differ, so if a charge ever appears, stop and confirm with Globe support or a store first. I cannot promise how any single case will go.
