0851 What Card and Which Area?

So, 0851 is the card prefix code Telkomsel. This means that numbers starting with 0851 use the Telkomsel network, one of the largest operators in Indonesia with extensive signal coverage.

Many people think that the number code always indicates a specific area. In fact, the number 0851 is not tied to a specific area.

You can activate a card with the prefix 0851 anywhere in Indonesia, from Sabang to Merauke, without location restrictions.

However, there's one interesting thing you should know. The three or four digits after 0851 (e.g., 0851-566 or 0851-701) are sometimes used as distribution or initial area codes when the card is first marketed. For example, certain digit combinations can point to Sulawesi, Java, or Sumatra.

However, this system isn't absolute. In today's era of online registration and digital distribution, area codes are no longer particularly relevant.

The 0851 number that was originally sold in Sulawesi may now be active and used in Jakarta or other areas.

So in conclusion, if you ask 0851 what card and which area, the answer is:

Telkomsel Card
Not tied to a specific region
Can be used throughout Indonesia

0851 is not a By.U number

Another question that often arises is, “0851 is By.U’s number, right?” The answer is: no.

Although By.U is on the same network as Telkomsel, the number codes used are different. By.U typically uses prefixes like:

0851 is not included in By.U
By.U use 0851 more often? (this is wrong)
The By.U prefix is generally 0851? Also not correct

The 0851 number belongs entirely to regular Telkomsel, not a By.U product. So if you receive an 0851 number, don't mistake it for a By.U number.

This distinction is important, especially if you want to check internet packages, customer service, or specific promotions. Regular Telkomsel and By.U have different systems and offers.
