How Samsung compares with the iPhone here
Counts are distinct handsets seen between 12 August and 10 November 2026. Samsung is our second-largest brand after Apple, with 1,230 phones against 5,686 iPhones. The mix is different: Samsung lookups lean towards locked phones and towards Vietnam.
| Lock reading | Samsung | iPhone (hub) |
|---|---|---|
| Locked to a carrier we read | 35 % of 1,230 | 26 % of 5,686 |
| Unlocked | 4 % | 11 % |
| Unknown | 61 % | 63 % |
The higher locked share is plausible because many US Galaxy lookups are for carrier-financed flagships. It is still a sample of people who chose to check, not of all Samsung phones.
US codes and international codes, side by side
Samsung sells the same flagship under several codes. This table pairs, for five families, the US carrier code (ending U) with the international code we saw most.
| Family | US code, devices | International code, devices |
|---|---|---|
| Galaxy S24 Ultra | SM-S928U, 35 | SM-S928B, 19 |
| Galaxy S25 Ultra | SM-S938U, 30 | SM-S938B, 23 |
| Galaxy S23 Ultra | SM-S918U, 26 | SM-S918B, 17 |
| Galaxy S22 Ultra | SM-S908U, 18 | SM-S908E, 11 |
| Galaxy S24 | SM-S921U, 17 | SM-S921B, 11 |
US codes outnumber international ones 126 to 81 across these five families. Two flagships have pages of their own: the S25 Ultra and S24 Ultra.
Where Samsung lookups come from
| Country of lookup | Samsung phones | Share of 1,230 |
|---|---|---|
| United States | 456 | 37 % |
| Vietnam | 280 | 23 % |
| United Kingdom | 40 | 3 % |
| France | 36 | 3 % |
| Canada | 34 | 3 % |
Vietnam is a bigger share here than for the iPhone, and nearly all of those read unknown. A buyer comparing a US-code phone with a Vietnam-sourced one should expect different bands; use the compatibility page.
Samsung-only things worth checking
- The model code. Read it in Settings, About phone, and match the ending to the market you will use it in.
- KG or Knox Guard. A financed phone can lock remotely. Read the KG lock page and ask for payment proof.
- Dual SIM, two IMEIs. *#06# should list both numbers.
- Blacklist and carrier. Run the blacklist check and the carrier lock check.

Questions people ask
Where do I find the IMEI on a Galaxy phone?
Samsung says to open <strong>Settings, About phone</strong> for the IMEI and model number, dial <strong>*#06#</strong> if your carrier allows it, or read the small print on the back. The <a href="/guides/find-imei/samsung">Samsung guide</a> covers dual-SIM models.
What do the letters at the end of an SM- code mean?
In our data the same flagship appears with a U ending for United States carrier builds and a B (often with -DS) for international builds, for example SM-S928U against SM-S928B. The code decides which bands and carrier software the phone has, so match it to your market.
Why are Vietnam lookups nearly all unknown?
Vietnam is our second-biggest Samsung country with 280 devices, mostly international builds. The free lookup reads the carrier lock only for T-Mobile and Metro phones, so those read unknown, not bad.
What is a Samsung KG lock?
Knox Guard locks a financed phone remotely when payments stop. A clean IMEI does not reveal it. The <a href="/check/samsung-kg">KG lock page</a> shows how to see it in the phone's settings.
Which Galaxy models have their own page?
The <a href="/check/galaxy-s25-ultra">S25 Ultra</a> and <a href="/check/galaxy-s24-ultra">S24 Ultra</a>, because they passed our minimum of 30 checked phones. Smaller models are not given pages we could not fill with real numbers.
