Macau eSIM: why ours is 4G and not 5G

If you found this page from a comparison table, our Macau card looks like the weaker option. Another eSIM in the same row says 5G and ours says 4G. We picked the 4G one on purpose, and this guide is the reason why. Read it and then decide, because for some trips the other card is the better buy.

What we sell, and what the other version is

soda’s Macau line rides CTM’s network in Macau, on 4G, over a roaming line that exits in Singapore.

The other version on the market exits in Hong Kong, rides both CTM and 3, and is labelled 5G. It carries one more host network than ours, its spec row looks better than ours, and it costs us less to buy. We took the first one anyway.

What an exit location is

Your phone connects to a tower in Macau. That part is not in question. The part in question is what happens next: where your data travels before it reaches the wider internet. Most travel eSIMs are roaming lines, so traffic goes back through a partner carrier’s system and comes out in some country. That country is the exit, and the services you use see an address there.

Ours comes out in Singapore. The other one comes out in Hong Kong. That single difference is what the whole trade is about.

Why the exit matters more than the 5G label

The 5G label is about peak speed, meaning how fast the line can go under good conditions. Everything you will actually do in Macau runs fine on 4G: maps, a ride, photos, a QR payment, a video. Missing the label will not strand you.

What slows you down in Macau is usually the crowd. At the border at peak hour, or around a packed hotel lobby, 4G and 5G are slow together.

The exit decides a different set of things. How far your traffic travels, and where the service on the other end thinks you are connecting from. None of that appears in the spec row on a product page, and all of it follows you for the whole trip. If you want to look up where a given line exits and which local networks carry it, we publish the exit database for 196 countries. The mechanics of roaming lines and the detour they add are in native versus roaming.

The honest limit of what we know

Here is the part most product pages leave out. We have not measured the addresses that the Hong Kong-exit line uses for Macau, so we do not put a customer’s trip on it. That is caution about something unmeasured, not a claim that the other line fails.

The same caution runs the other way. We do not promise that any specific app or service will work on our line either, because that depends on network conditions at the time and is not something anyone can sign for. What we can tell you is exactly which network carries you and where you come out, which is what this page has done.

Who should not buy this card

Anyone whose trip genuinely needs 5G. If you are streaming at high bitrate from the venue, or you have a hard requirement on peak speed, buy the version with the 5G label. We would rather lose that sale than have you find out after landing.

No single card serves every traveller well. The choice we made is to put the trade in front of you before you pay.

Hong Kong and Macau are two cards

Most visitors pair Macau with Hong Kong. Those are separate single-country lines, so that is two cards. You switch once in the app before you cross, there is no service fee, and the new card is confirmed working before the old one stops. The wallet and the balance are shared, so both halves of the trip sit on one account. Hong Kong’s tiers are on the Hong Kong destination page.

If you cross from Macau into mainland China, same story again: another line, another switch.

The practical version for a day trip out of Hong Kong is this. Do the switch while you are still on the Hong Kong side with working data. Install the Macau card, confirm it connects, and only then stop the old one. Doing it the other way round leaves you with no data at the crossing, which is exactly when you want to check transport. Save a screenshot of the return ferry or bus times while you are at it.

How much data a day in Macau uses

Macau is small and the sights sit close together. Most visitors spend the day walking between a few places, checking routes, taking photos and messaging whoever they came with. That lands under 1GB for a normal day, and less again if the afternoon is spent inside a hotel on its Wi-Fi.

The heaviest stretch is usually the border itself. Everyone crossing at the same time is looking up transport and calling the people they got separated from, which is the moment you want data already working rather than the moment to start installing something.

Short trips are where the wallet earns its keep

A one or two day trip is the easiest kind to buy wrong. 1GB feels too small, 3GB goes unused, and a day trip is hard to size in advance because half of it gets decided over breakfast.

soda has no minimum. You use 300MB, you pay for 300MB, and at settlement the system applies the cheapest combination of plans in retrospect. Whatever is left over does not expire and is still there on the next trip, so a two-day trip does not end with a bundle you paid for and threw away. What happens to leftover data goes through it properly.

How soda works in Macau

Land, open it, get billed on what you used. The current tiers are on the Macau destination page, along with the host network in Macau and where the line exits.

We will not tell you this is the best Macau card on the market. It is 4G, and it will lose a comparison row to the cards with the 5G label. We think the exit location matters more than that label, so we made the trade, and we put the reasoning here so you can judge it yourself.
