Our verdict
The Unihertz Jelly 2E is a reasonable second phone if you want the smallest Android phone you can still buy new, mainly for calls, messages, music and maps on T-Mobile. We would not buy it as a primary phone, for contactless payments, or for AT&T or Verizon service. Its appeal is a 3-inch screen, a 110-gram body, a headphone jack, an IR blaster and a $149.99 price. Its costs are frozen software, no NFC, an entry-level chip, a hard-to-use keyboard and strict return terms.
Research-based review · Not scored · Checked November 7, 2026. We have not used a Jelly 2E. This assessment compares Unihertz’s product page, store data and policy page with launch coverage and one hands-on review. It contains no FlawCheck battery, performance, camera, network or durability measurements.
This review covers the Unihertz Jelly 2E with 4GB of RAM and 64GB of storage, sold on Unihertz’s store as the US region variant. It does not cover the older Jelly 2 or the newer Jelly models. The 2E is a cheaper follow-up to the Jelly 2, not an upgrade. [1][2]
Consider it on T-Mobile for calls, music and a few light apps, alongside a main phone.
Check the carrier first. The small battery and frozen software matter less for short, light use.
Avoid. Android 12 with no further OS upgrades, no NFC and a slow chip make it a poor main device.
Three takeaways govern this review: Unihertz itself says the Jelly 2E will get no further OS upgrades; “compatible” with AT&T and Verizon comes with footnotes that matter; and a refund requires an unopened box.
Strengths and weaknesses
The strongest reason to consider the Jelly 2E is size. Few new Android phones are this small, and it keeps a 3.5mm headphone jack, an infrared blaster and a programmable red key. Those are the things it does that a mainstream phone does not.
- 3-inch screen and 110g body
- Typing on the small keyboard is error-prone, and some apps do not fit the screen.
- $149.99 for a new phone
- Android 12 with no further OS upgrades from Unihertz.
- Dual SIM, microSD, headphone jack, IR blaster
- No NFC, and the memory card takes the second SIM slot.
- 4G LTE with a US carrier list
- AT&T depends on a whitelist and Verizon will not activate a new SIM in it.
These are reasons to investigate or avoid a purchase. They are not measured failure rates. Most of the risk comes from the phone’s age and the carrier terms, not from its basic design.

Design and portability
The phone measures 93 × 48 × 16mm according to Parka Blogs’ hands-on review, and Unihertz’s store data lists a weight of 110 for the phone, the same 110 grams that Notebookcheck reports. We have not weighed or measured a unit. [1][2]

It fits a coin pocket. The trade-off is a keyboard that is hard to type on and a small battery.
Parka Blogs found the USB-C port on the right side, so “it’s not easy to use the phone while charging”. It also reported that “Fingerprint unlock may sometimes take a few tries”. The reviewer called the plastic body “reasonable build quality”. Unihertz does not list a water or dust rating for the Jelly 2E, and we found none. [1]
Unihertz lists a 3.5mm headphone jack, an infrared port for remote control and its programmable red key. These are real extras for a phone this size. We have not tested the IR blaster with any device. [1]
Display and everyday usability
Unihertz describes “The 3.0-inch sized Jelly 2E phone”, and Liliputing reports an 854 × 480 LCD. That is enough for messages, music controls and turn-by-turn directions. It is small for reading, video or photos. [1]
The main usability problem is typing. Parka Blogs wrote that “Typing the wrong letter is common” and listed “Not all apps will work or display well on a small screen” among its cons. Voice typing and short replies are the practical way to use it. Plan on apps built for 6-inch screens feeling cramped. [1]
Performance, memory and storage
The Jelly 2E uses a MediaTek Helio A22 with four Cortex-A53 cores, according to Liliputing and Notebookcheck. Liliputing said “the older model is still the better buy: it has a faster processor, more memory, and more storage”. Parka Blogs’ review names a different chip, which conflicts with both reports. We use the Helio A22. [1]
Parka Blogs found that “Apps run smooth” in daily use, but that games with heavy 3D graphics “will struggle”. We have no benchmark or performance test. Our guide on what makes a phone fast explains why an entry-level chip can feel fine for messaging and slow for anything heavier. [1]
Memory is 4GB of RAM and 64GB of storage. Unihertz says you can “equip one memory card to expand your storage to 512GB and more”, but the phone has “dual sim cards with the hybrid sim slot”, so a card takes the place of the second SIM. Our guide on how much RAM an Android phone needs puts 4GB in context. [1]
Cameras
Parka Blogs reports a 16MP rear camera and a 12MP front camera. It described front-camera image quality as “alright (budget-phone standard) with good light” and rear photos as “decent with good light”. It also noted that details are hard to judge on a 3-inch screen. We have not seen enough independent samples to judge the cameras, and we would not buy this phone for photography. [1]
Battery and charging
Unihertz lists a 2,000mAh battery and says “your basic daily use can be covered in one full charge”, based on its own lab tests. Parka Blogs reported “about 5+ hours at maximum brightness”. Notebookcheck warned that the small battery could be a problem in practice. Unihertz does not state a charging speed. We have no FlawCheck battery or charging measurement. [1][2]
Connectivity, software and ownership
US carriers: read the footnotes
Unihertz lists T-Mobile, Verizon and AT&T, but its own footnotes limit two of them. AT&T is “only compatible with whitelisted Unihertz devices (Jelly 2, Titan 2, etc.)”, and the Jelly 2E is not named in that example. For Verizon, Unihertz says the phone “is not certified by Verizon, you cannot activate your new SIM card with it”. Twelve smaller carriers on the list are marked “This MVNO may not work properly with Unihertz devices”. [1][2]
What Unihertz says about each US network.
- T-MobileListed without a footnoteListed
- AT&T"only compatible with whitelisted Unihertz devices (Jelly 2, Titan 2, etc.)"Whitelist
- Verizon"not certified by Verizon, you cannot activate your new SIM card with it"No new SIM
- 12 smaller carriers"This MVNO may not work properly with Unihertz devices"May not work
Unihertz does not accept returns over carrier compatibility. Check the IMEI with your carrier before ordering.
Unihertz also says: “We do not accept return requests related to carrier compatibility issues.” We could not read an official band list, and we did not check an IMEI or activate a unit. Check the IMEI with your carrier before you order, because a carrier problem is not a reason for a refund. [1]
No NFC, and Google Pay may not work
The Jelly 2E has no NFC, so it cannot make contactless payments. Parka Blogs and Liliputing both note that the older Jelly 2 had NFC and the 2E does not. Unihertz’s product page adds that “Google Pay may not function properly on this device”. [1][2]
Software is frozen at Android 12
The phone ships with Android 12, which Google released in 2021. Unihertz’s own product page says: “Due to the legacy Android version and the lack of MediaTek platform development support, this device cannot receive further OS upgrades.” We found no Unihertz commitment for security patches or a support end date, and we could not confirm the installed patch level. [1][2]
That makes the Jelly 2E a poor home for banking, work or password apps. Apps drop support for old Android versions over time. Our guide to phones for long-term ownership explains why the support window matters more than the purchase price.
Warranty and returns favor unopened boxes
Unihertz’s warranty, return and refund policy gives smartphones a “12-Month Warranty”, limited to the country of purchase. Accessories get one month. [1]
For a return without a defect, “The smartphone must be unused and in its original, unopened packaging”, and devices “that have been unboxed, activated or used are not eligible for a refund”. The buyer pays return shipping, and the refund excludes shipping fees. The policy does not state a number of days for these returns. In practice, you cannot try the keyboard or a SIM card and still get your money back. [1][2]
Alternatives and value
Our reference offer is the US region variant on Unihertz’s store at $149.99, with a crossed-out $169.99. All four region variants show the same price. This is a storefront observation from November 7, 2026, not a delivered total. [1][2]

|---|---|---|
| Unihertz store, US variant | $149.99, compare-at $169.99 | Listed as in stock |
| Launch (November 2022) | $169 list price, early-bird $139 | Historical, not today’s price |
| Shipping | Free on phone-only orders over $99 in the USA | Product page banner |
| Returns without a defect | Unopened box only; buyer pays shipping | Refund policy |
| Delivered total | Not checked | Unavailable |
We have no verified delivered total. Discount codes on Unihertz’s store change often and are not included here. A crossed-out price is not a saving we can verify.
The alternatives depend on why you want a small phone. If you want a light phone for a run or a night out, a basic phone with calls and texts avoids the frozen-software problem altogether. If you want a main phone, a current mid-range Android with a stated update period is the safer choice, even if it is twice the size. Unihertz also sells newer Jelly models; we have not reviewed them.
Three ways to carry less.
Final verdict
Consider the Jelly 2E if you want a second phone the size of a credit card for calls, music and a few light apps, you use T-Mobile, and you accept that its software will not be upgraded. Check the IMEI with your carrier and read the return terms before you order, because carrier problems and opened boxes are not refunded.
If you need a primary phone, contactless payments, AT&T or Verizon, comfortable typing or years of updates, we would choose a different device. We are withholding a numerical score because we have not tested the phone or verified a full transaction.
Frequently asked questions
Will the Jelly 2E get Android 13? No. Unihertz says the phone cannot receive further OS upgrades. We found no security-patch commitment either.
Does the Jelly 2E work on AT&T or Verizon? Unihertz says AT&T works only with whitelisted devices and does not name the 2E, and that a new Verizon SIM cannot be activated in it. T-Mobile is the safer choice. We did not test any carrier.
Does it have NFC for Google Pay? No. The Jelly 2E has no NFC, and Unihertz says Google Pay may not work properly.
Is the Jelly 2E faster than the Jelly 2? No. Launch coverage reports a slower Helio A22 chip, less memory and less storage than the Jelly 2.
Can I return it if I don’t like the small screen? Only if the box is unopened. Opened or activated phones are not eligible for a refund, and you pay return shipping.
