Is the vivo X300 Ultra Compatible With US, European, Middle East & Japan Carriers? (2026 Band Guide)
The vivo X300 Ultra (China model V2547A / V2547DA) has very broad 4G and 5G band support. It is an excellent fit across Europe, the Middle East, Canada and Japan, and it works well across the US too — it has AT&T’s B2/4/5/12 with n5 and n77 5G, T-Mobile’s n41 mid-band 5G, and Verizon’s n77/n78. The phone is unlocked, runs OriginOS 6 (Android 16), and Google services are easy to add. The one thing to note: Verizon lacks the phone’s key 700 MHz band and whitelists devices, so Verizon users should check first.
The bands the vivo X300 Ultra supports
These bands come directly from vivo’s official specification for the China model (V2547A / V2547DA):
- 2G GSM: 850 / 900 / 1800 / 1900 MHz
- 3G WCDMA: B1, B2, B4, B5, B6, B8, B19
- 4G FDD-LTE: B1, B2, B3, B4, B5, B7, B8, B12, B17, B18, B19, B20, B25, B26, B28, B66
- 4G TD-LTE: B34, B38, B39, B40, B41, B42, B43, B48
- 5G NR: n1, n2, n3, n5, n7, n8, n12, n18, n20, n25, n26, n28, n38, n40, n41, n48, n66, n77, n78, n79, n80, n81, n83, n84, n89
All 5G here is sub-6 GHz — there is no mmWave. The phone does not carry B13 (Verizon 700 MHz) or B71 / n71 (T-Mobile 600 MHz).
Carrier compatibility
| Region / Carrier | vivo X300 Ultra | What to expect |
|---|---|---|
| US — AT&T | LTE B2/4/5/12/17/66; 5G n5, n77 | Works on AT&T’s main 4G and 5G bands, including C-band 5G. |
| US — T-Mobile | LTE B2/4/5/12/66; 5G n25, n41 | Strong mid-band 5G via n41. No 600 MHz (n71), so far-rural and deep-indoor coverage is a little weaker. |
| US — Verizon | LTE B2/4/5/66; 5G n2, n5, n77, n78 | Missing Verizon’s key B13, and Verizon whitelists devices — check with Verizon whether a phone with these bands can be activated on your line. |
| Canada — Rogers / Bell / Telus | LTE B2/4/5/7/12/17/66; 5G n5, n7, n38, n66, n77, n78 | Good 4G and 5G coverage across Rogers, Bell and Telus. |
| Europe — UK, Germany, France, Italy, Spain, Switzerland & more | LTE B1/3/7/8/20/28/38/40; 5G n1, n3, n7, n8, n28, n38, n78 | Excellent — covers the standard European bands used by EE, Vodafone, O2, Three, Deutsche Telekom, Orange, Movistar, TIM, Swisscom and other regional carriers. |
| Middle East — Israel, UAE & wider GCC | LTE B1/3/7/8/20/28/40/41; 5G n1, n3, n28, n77, n78 | Strong fit for Israel (Partner, Cellcom, Pelephone), the UAE (Etisalat, du) and the wider GCC such as STC. |
| Japan — Docomo / au / SoftBank / Rakuten | LTE B1/3/8/18/19/26/28/41/42; 5G n1, n3, n28, n77, n78, n79 | Supports n79, which Japan uses heavily, plus n77 and n78. |
What this means for you
Great fit: buyers across Europe (UK, Germany, France, Italy, Spain, Switzerland and more), the Middle East, Canada and Japan, and US users on AT&T or T-Mobile.
Just check first: Verizon users — the phone lacks Verizon’s key 700 MHz band (B13) and Verizon restricts which devices can activate, so confirm with Verizon before buying.
China version, OriginOS 6 & Google services
This is the China model (V2547A / V2547DA) running OriginOS 6, based on Android 16. Google Mobile Services (GMS) come pre-installed from the factory, so Google’s core services are already on the phone. Adding the Google Play Store is quick and easy to do yourself once it arrives — no technical steps needed. The phone is unlocked.
