Personal Argentina roaming in USA 2026 — eSIM from $5

If you're traveling from Argentina to the United States and use Personal, international roaming costs $6 per MB without an additional plan — a 100 MB download can run $600 ARS. In this post we compare Personal Argentina's roaming rates for USA in 2026, show the real cost of calls and data, and present the local eSIM alternative we use at eSIM Ahora: T-Mobile or AT&T network from $5-$12 per 5 GB, active in 30 seconds, with no FUP throttling.

Personal Argentina rates in USA (roaming)

Personal offers automatic roaming in the United States through agreements with T-Mobile, AT&T, and Verizon. Rates current as of August 2026 are:

Personal does not apply throttling or cutoff by volume — you pay for actual consumption. A typical day of moderate use (200 MB of WhatsApp, maps, navigation) costs $1,200 ARS in data alone. If you stream video or upload photos without WiFi, costs escalate quickly: 1 GB = $6,000 ARS.

Personal roaming packages

Personal sells two prepaid packages for USA:

• 7-day Roaming Package: $3,500 ARS — includes 500 MB + 30 min of calls + unlimited SMS.
• 15-day Roaming Package: $6,000 ARS — includes 1 GB + 60 min of calls + unlimited SMS.

Both packages activate from the Mi Personal app or by dialing *555. Activation takes up to 4 hours. Data overage is charged at $6/MB.

Key limitation: packages do not auto-renew. If you travel 10 days, you must buy the 15-day package (you cannot stack two 7-day packages).

How Personal roaming works in USA

When you land in the United States, your phone searches for network automatically. Personal has agreements with:

• T-Mobile (nationwide coverage, 4G LTE in 99% of urban areas, 5G in major cities).
• AT&T (superior rural coverage in Texas, Montana, Dakotas).
• Verizon (premium network, rarely assigned to roaming customers).

Most users connect to T-Mobile by default. You can force the network manually in Settings > Connections > Mobile networks > Network operators.

Speeds: Personal does not limit speed on roaming — if you connect to T-Mobile 5G, you get the native network speed (up to 300 Mbps in 5G UC areas). The real limit is your consumption: at $6/MB, nobody runs speed tests.

Roaming activation

International roaming comes activated by default on Personal postpaid lines and Arnet Móvil. On Personal prepaid lines, you must enable it:

1. Dial *555 from Argentina BEFORE traveling.
2. Select "International roaming".
3. Confirm with your 4-digit PIN.

Activation is instant. If you don't do it before traveling, you can activate from USA by dialing *555 (charged as a local roaming call, ~$9 ARS/min).

eSIM Ahora in USA — roaming-free alternative

At eSIM Ahora we use T-Mobile network (primary) and AT&T (backup in rural areas where T-Mobile doesn't cover). Plans are optimized for travelers from Argentina:

• Price range: $5-$12 for 5 GB (see current USA plans).
• Activation: scan the QR from the app, the line activates in 30 seconds. No calls or 4-hour waits.
• FUP throttling: we do not apply cutoff or speed reduction. 5 GB at full 4G LTE.
• Coverage: 99% of interstate highways, major cities (New York, Los Angeles, Miami, Chicago, Houston), national parks with towers (Yellowstone, Yosemite, Grand Canyon at access points).

Typical use case: 7-day trip to Florida (Miami, Orlando). With Personal 7-day package you pay $3,500 ARS for 500 MB. With eSIM Ahora you pay ~$8 USD (equivalent to $8,000 ARS at August 2026 rates, but with no 500 MB limit — the plan includes 5 GB).

Direct comparison: Personal vs. local eSIM

Honest trade-off: Personal includes cellular voice minutes (useful if you need to call a USA number that doesn't use WhatsApp, like hotels or rental cars). eSIM Ahora is data-only — for calls you use VoIP (WhatsApp, Telegram, Skype). If your trip requires frequent calls to local numbers without apps, Personal's package may make sense; if your use is 95% data (maps, social media, email), the local eSIM costs less.

Real coverage in key USA destinations

The T-Mobile network (what we use at eSIM Ahora) covers:

• New York: 5G in Manhattan, Queens, Brooklyn; 4G LTE in New Jersey suburbs.
• Los Angeles: 5G in Downtown LA, Santa Monica, Beverly Hills; 4G LTE in valleys (San Fernando, Inland Empire).
• Miami/Fort Lauderdale: 5G in South Beach, Downtown Miami, Brickell; 4G in Everglades (intermittent in swamp areas).
• Orlando: 5G on International Drive, Disney, Universal parks; 4G on I-4, Florida Turnpike.
• Las Vegas: 5G on The Strip, Downtown; 4G in surrounding desert (Hoover Dam has coverage, Death Valley does not).
• San Francisco: 5G in Embarcadero, Financial District, SOMA; 4G in Marin County, Napa Valley (gaps in Big Sur mountain areas).

T-Mobile no-coverage zones: rural parts of Montana, Wyoming, West Virginia, Maine. In those areas AT&T covers better — you can manually switch networks in Settings if your phone allows it (some eSIMs allow manual selection, others stay fixed to T-Mobile).

Personal, roaming across three networks (T-Mobile + AT&T + Verizon), has slightly better coverage on rural routes. If you plan a road trip on Route 66 or through the Rocky Mountains, Personal roaming may give you more signal continuity.

How to buy and activate an eSIM for USA from Argentina

If you decide to use a local eSIM instead of Personal roaming:

1. Verify compatibility. Your phone must support eSIM: iPhone XS/XR or later, Samsung Galaxy S20 or later, Google Pixel 3 or later. Check your manufacturer's full list.
2. Buy the plan. Go to USA plans, select data volume (3 GB, 5 GB, 10 GB) and validity (7, 15, 30 days).
3. Receive the QR. It arrives by email in under 2 minutes. The QR is valid for 12 months — you can buy it before traveling.
4. Scan the QR. From Settings > Connections > SIM manager > Add mobile plan (Android) or Settings > Mobile data > Add data plan (iPhone). Scanning takes 10 seconds, network activation takes another 20 seconds.
5. Set eSIM for data. Once installed, go to Settings > Connections and mark the eSIM as primary line for mobile data. Keep your Personal physical SIM active to receive SMS verification from Argentine banks (roaming SMS don't charge at Personal).

Dual-SIM tip: keep Personal active ONLY for SMS (disable mobile data on that line). That lets you receive 2FA codes from Mercado Pago, Brubank, BBVA HomebanKing without charge, while all data flows through the local eSIM.

Invoice and VAT deduction for self-employed

If you're self-employed registered in Argentina and need an invoice to deduct the expense:

• Personal: issues invoice A or B per your tax status. Roaming charges appear on your monthly statement as "International services". 100% deductible if the trip is work-related (keep boarding passes and event/meeting justification).
• eSIM Ahora: we issue electronic invoices within the EU (Spanish tax ID). For Argentine self-employed, the invoice serves as proof of foreign-currency spending — AFIP accepts foreign supplier invoices if service was consumed outside Argentina. Consult your accountant if you need additional validation.

Personal's advantage is the invoice comes in ARS and stays in the Argentine system from the start. eSIM Ahora's advantage is lower cost, so the deduction is smaller but net savings are larger.

What to do if Personal roaming doesn't work in USA

Common issues and fixes:

No signal on landing:

1. Turn airplane mode on and off — forces a fresh network search.
2. Restart your phone.
3. Go to Settings > Mobile networks > Network operators > Search networks. Manually select T-Mobile or AT&T.

Signal shows but no data:

• Verify Roaming data is on: Settings > Connections > Mobile networks > Data roaming (must be ON).
• Check the APN: should say datos.personal.com. If missing, add manually (Settings > Access Point Names > New APN).

Unexpected charges:

• If you bought the 7-day package but keep getting per-MB charges, call *611 from USA (free) or +54 11 4444 1000 via WhatsApp. Personal has 24/7 roaming support, but wait times can be 20-40 minutes.

Comparison with other eSIM providers for USA

Beyond Personal and eSIM Ahora, other options for USA data:

• Airalo: charges $4.50 per 1 GB in USA (as of May 2026), uses AT&T network. Does not offer invoices. Support only via chatbot.
• Holafly: charges $19 for 5 days with unlimited data in USA, but applies FUP throttling at 2 GB daily (speed drops to 1 Mbps after 2 GB/day). Has 24/7 support via chat in Spanish.

Among travel eSIM providers, Airalo has the broadest country coverage (190+), but in USA its price per GB exceeds eSIM Ahora's. Holafly offers "unlimited" data with the asterisk of throttling — useful if you stream heavy video, but post-FUP speed (1 Mbps) barely handles email and maps.

Personal Argentina charges more than a local eSIM but less than Holafly if you only need 500 MB–1 GB for a short trip. If your consumption is low (just WhatsApp and Google Maps), Personal's 7-day package at $3,500 ARS may suffice.

FAQ

Does Personal roaming work throughout the United States?

Yes, Personal's roaming coverage reaches 99% of populated US territory through agreements with T-Mobile, AT&T, and Verizon. Remote rural areas (parts of Montana, Wyoming, Alaska) may have gaps, same as any local operator.

Can I use my Personal Argentina data package in USA?

No, the gigas included in your Personal Argentina plan do NOT work on roaming. You must buy a specific roaming package ($3,500 ARS for 7 days with 500 MB, or $6,000 ARS for 15 days with 1 GB) or pay per-MB consumption at $6 ARS/MB.

What happens if I use up my roaming package data?

If you exhaust the 500 MB or 1 GB package, Personal continues charging data at standard roaming rate: $6 ARS per MB. No service cutoff. You can buy another plan from the Mi Personal app, but they're not stackable — if you buy a second 7-day package, it replaces the first, it doesn't add gigas.

Does the eSIM replace my Personal physical SIM?

No, the eSIM is an additional line that coexists with your physical SIM. On a dual-SIM phone (physical + eSIM), you can keep Personal active for calls and SMS, and use the eSIM for data only. This lets you receive SMS from Argentine banks for free (roaming SMS don't charge at Personal) while browsing on the local eSIM rate.

How long does Personal's roaming package take to activate?

Activation can take up to 4 hours from when you buy it in the Mi Personal app. We recommend activating it BEFORE leaving Argentina to avoid delays. If you activate already in USA, wait time is the same (up to 4 hours), during which you're charged standard roaming ($6/MB).

Can I make calls with a data-only eSIM?

Data-only eSIMs (like USA plans) do not include a phone number for traditional cellular calls. You can make calls over the internet using WhatsApp, Telegram, Skype, Google Meet, or FaceTime — all work on the eSIM's data. If you need to call a local USA number that doesn't use apps (hotel, rental car), you must use your Personal SIM on roaming (charged $9 ARS/min).
