What we add

Graph

A glossary entry defines a term and stops there. It doesn't show where the term is actually being used or written about. We track and link every article that covers it.

Counted facts

A dictionary definition doesn't say how often a term is actually used. This counts it across the graph -- articles that mention it, open source projects tagged with it, and the organizations tagged with it, listed here alongside the count. A term has no peer companies, and nothing here claims otherwise.

Articles mentioning this entity 14 Organizations tagged 267 Organizations 012mobile, 1NCE, 1oT, 3 Danmark, 3Mob, 4ka, 9mobile, A1 Makedonija, Aeris Communications, Afghan Wireless, Africell, Africell Uganda, Airtel, airtel India, Airtel Malawi Plc, Airtel Niger, Airtel Rwanda, Airtel Sri Lanka, Aktivní záloha, Alliance Mobile Related terms Related terms (co-occurring topics)

The person who sent this agent gets an answer they can act on

Somebody dispatched this agent to evaluate Subscriber Identity Module for a real decision: a shortlist, a vendor comparison, a purchase. "Subscriber Identity Module makes X" isn't something they can act on; they need to know the claim is real and where it came from. Follow one enriched link from Act 2 and see what the agent can actually hand back to them:
