Knowing the mobile prefix number of someone you want to call or text can help you in many ways.

If you know the prefix of the person you want to reach you can pick the promo that fits best and not waste your money.
Avoid Scam Numbers. Some scammers use fake numbers to trick people. If you know which prefix belongs to which network you can spot something unusual right away.

Useful for Business Owners. If you run a small business and you call customers every day to knowing prefixes helps you manage your communication costs. You can group your contacts by network and use the best promos for each group.
