Mistakes When Buying a SIM Card in the Philippines

Traveling to the Philippines? One of the first things most travelers do upon landing is buy a local SIM card to stay connected. While the process might seem simple, there are common pitfalls that can cause you to waste money, experience poor connectivity, or even face legal issues. Here’s a detailed look at the most common mistakes when buying a SIM card in the Philippines — and how to avoid them.

1. Not Bringing a Valid ID for SIM Registration

Since December 2022, the Philippines has enforced the SIM Registration Act, requiring all SIM card users — including foreigners — to register their SIM with a valid ID.

Common Mistake:

Tourists assume they can just pop a SIM into their phone and go. In reality, without ID verification, your SIM will be deactivated within a certain period.

How to Avoid:

Bring a valid passport. Some providers may also ask for proof of entry (e.g., your arrival stamp or e-ticket).

Register the SIM immediately upon purchase. Most retailers will assist with this.

2. Buying from Unofficial or Unreliable Sellers

While you can find SIM cards at airports, street kiosks, convenience stores, and online, not all sellers are authorized or trustworthy.

Common Mistake:

Buying a SIM from an unverified seller may result in an inactive, already-registered, or even cloned SIM.

How to Avoid:

Buy from official kiosks at the airport (Globe, Smart, DITO).

If in the city, go to official branches or authorized dealers like SM Malls, 7-Eleven, or Robinsons.

3. Choosing the Wrong Network for Your Location

The Philippines has three major networks: Globe, Smart, and DITO. Their coverage and performance vary depending on location.

Common Mistake:

Assuming all networks have equal coverage nationwide. Tourists often buy what's cheapest or what's offered at the airport without checking coverage.

How to Avoid:

Research which provider works best in the area you’ll be staying (e.g., Smart is better in rural Mindanao, while Globe may be better in parts of Luzon).

Ask locals or your hotel staff for recommendations.

4. Not Understanding the Data Packages

Philippine telecoms often offer a dizzying array of prepaid promos (e.g., GoSURF, Giga, UNLI5G). Some plans are app-exclusive or time-limited.

Common Mistake:

Choosing a promo without knowing the data cap, speed limit, or app restrictions (e.g., some promos give data only for Facebook or TikTok).

How to Avoid:

Ask for a data plan that includes open access (not app-restricted).

Install the telco’s official app (GigaLife, GlobeOne, DITO) to manage your plan and monitor usage.

5. Ignoring Dual SIM Compatibility and Locking Issues

Some phones, especially those from overseas, may be locked or not compatible with local frequency bands.

Common Mistake:

Bringing a locked phone or one that can’t use Philippine network frequencies.

How to Avoid:

Make sure your phone is unlocked and supports 4G LTE bands 3, 5, 28, or 5G n78.

If your phone is dual-SIM, check whether both slots support data. In some models, only one slot supports 4G.

6. Not Monitoring Expiry or Auto-Disconnection Rules

Philippine SIMs can get deactivated if unused for a certain period, and some data promos are valid for only 1–7 days.

Common Mistake:

Thinking the SIM will stay active indefinitely. Travelers often top up once and expect it to work weeks later.

How to Avoid:

Track promo expiry using SMS or the telco app.

Load small amounts regularly to keep the SIM active if you’ll be in the country long-term.

7. Not Asking About Tourist-Specific SIM Offers

Some telcos offer tourist bundles with generous data allowances, airport pickup, or travel perks.

Common Mistake:

Purchasing a regular SIM instead of a tourist-friendly bundle.

How to Avoid:

Ask for a “Tourist SIM” at official counters.

Look for packages like Globe Traveler SIM or Smart Welcome SIM, which include data, calls, and sometimes freebies.

8. Relying Solely on Mobile Data Without Offline Backups

Network coverage can be spotty in certain islands, provinces, or mountainous areas. 

Common Mistake:

Expecting consistent mobile internet everywhere.

How to Avoid:

Download offline maps (Google Maps, Maps.me).

Save essential info like hotel bookings and travel documents locally on your phone.

9. Forgetting to Bring a SIM Ejector Tool

Switching SIMs is easy — if you have a pin.

Common Mistake:

Travelers forget to bring a SIM ejector tool, especially those with iPhones or newer Androids.

How to Avoid:

Bring a SIM ejector pin or paperclip.

Ask your SIM seller to help insert and activate the card.

10. Failing to Check for Hidden Charges

Telcos may deduct prepaid balance for services like voicemail, spam texts, or automatic subscriptions.

Common Mistake:

Suddenly losing load (credit) without understanding why.

How to Avoid:

Immediately disable voicemail and mobile data if not using it.

Opt out of unnecessary services via SMS commands or the telco app.
