Getting a U.S. Phone Number: What You Need to Know

When you arrive in the U.S., you will probably want a local phone number so you can stay connected, use maps, get important college updates, and contact friends and family. In the U.S., you can choose between traditional phone companies (like Verizon, AT&T, and T-Mobile) or smaller, low-cost companies called MVNOs that use the big networks but offer cheaper, flexible plans. You can buy a physical SIM card or, if your phone supports it, activate an eSIM so you can set everything up quickly.

Plans come in two main types: monthly contracts, which often require a credit check, and prepaid or pay-as-you-go plans, which are more flexible and usually a better fit for students who don’t have a U.S. credit history. The best option depends on your budget, how long you’ll be in the U.S., and how much data you need—but this guide walks you through the basics so you can choose the plan that works best for you.

General Information About Cell Phones in the US

  1. SIM Cards + Phones
    • If you bring your own phone: It must be unlocked. Otherwise, SIM from a U.S. carrier may not work.
    • If you do not bring one: You can buy a physical SIM in the U.S., or use an eSIM (if your phone supports it).
  2. Network Coverage
    • The “big three” carriers are AT&T, Verizon, T-Mobile. Many smaller providers (MVNOs) use these networks.
    • For students, choosing a reliable MVNO (Mint Mobile, Ultra Mobile, Boost Mobile) can offer good coverage + much lower cost than big-name postpaid carriers.
  3. Monthly Contract (Postpaid) vs. Prepaid / Pay-as-You-Go
    • Monthly Contracts (Postpaid): Traditional phone plans where you pay each month, often need a credit check, sometimes require a deposit, and may lock you into a line for longer.
    • Prepaid / Pay-as-You-Go: No long-term contract, typically no credit check, and more flexible.
      • Pros: Flexibility, no credit requirements, good for students who may only want a U.S. number for a year or less.
      • Cons: You often pay full price up front for the phone (if you buy a phone), and data or minute costs can sometimes be higher per unit if you’re using a lot.
  4. eSIM vs Physical SIM
    • eSIMs: Great for students who arrive and want connectivity immediately. You can often order and activate before landing, and there’s no need to go to a store.
    • Physical SIM: More traditional; might be cheaper for very long-term staying, or if your phone does not support eSIM.
  5. Documentation + Activation
    • Prepaid plans are often easier to get going because they do not always require a Social Security Number or credit history.
    • However, you should confirm with the provider: whether you need an ID, any deposit, or a U.S. address.
Pros & Cons Specifically for International Students

Why many international students might lean toward prepaid / MVNO:

  • Flexibility → No long-term contracts – great if you plan to only be in the U.S. for 1-4 years.
  • Cost control → Cheaper prices, pay for exactly what you need, no surprise “bill shock.”
  • Good data + global calling options (with certain MVNOs).
  • No credit checks or credit history required → easier to signup
  • Often available as SIM kits at stores like Walgreens, Target, Best Buy, or online

Why some international students might prefer a contract plan: 

  • If you plan to stay many years, a postpaid “contract” plan might offer better long-term deals / subsidized phones (but this is less common now).
  • Bigger providers may have better network coverage in rural areas; some MVNOs are good in cities but not everywhere. In crowded areas, the “main carrier” customers sometimes get network priority. Most students never notice.
  • For eSIM: your phone must support it.

Locals Say:

  1. Bring IMEI / phone model info — When you arrive, you should check whether your phone is compatible with U.S. networks (bands) before buying a SIM.
  2. SIM in advance — If possible, order a SIM card (or eSIM) before arrival so you can use your phone immediately.
  3. Use Wi-Fi when possible — On campus, you can use Wi-Fi, so you may not need to use a lot of mobile data.
  4. Consider calling apps — Use WhatsApp, Telegram, Skype, etc., to call home — this can significantly reduce costs.
  5. Top up smart — For prepaid, you should monitor data usage and make sure to top up; for plans paid in advance (like Mint), they’re locked in for a period.
  6. Check student or international deals — Some carriers / MVNOs may have promotions or discounts for students.
