Red Pocket is unusual among MVNOs because it operates across all four major US networks. When you sign up, you pick which network you want, and Red Pocket ships a SIM provisioned specifically for that one. The APN values change for each underlying network, so the right configuration depends on which Red Pocket SIM you got.
Here is the verified setup for each network plus how to figure out which one your Red Pocket line is on.
Red Pocket Network Overview
- Red Pocket runs on AT&T, Verizon, T-Mobile, and the former Sprint network (now part of T-Mobile). Lines are network-specific; you cannot swap networks without a new SIM.
- Red Pocket uses different APN values for each network. AT&T (GSM-A): RESELLER. Verizon (CDMA-V): typically auto-configures, no manual APN. T-Mobile (GSM-T): wholesale or fast.t-mobile.com.
- Most modern phones auto-configure Red Pocket when the SIM activates, especially iPhones. Manual entry is mainly needed on older Android devices or imports.
- 5G coverage on Red Pocket matches the underlying network's 5G footprint. The same APN handles 4G LTE and 5G traffic.
Opening the APN Screen
Identify your underlying network first. The Red Pocket SIM packaging is labeled GSM-A (AT&T), CDMA-V (Verizon), GSM-T (T-Mobile), or CDMA-S (legacy Sprint, now T-Mobile). The label tells you which APN list applies.
Android
- 1.Open Settings
- 2.Tap Mobile Networks, then RedPocket SIM Settings (or your Red Pocket SIM in dual-SIM mode)
- 3.Tap Access Point Names
- 4.Tap the + button or three-dot menu, then New APN
- 5.Enter the values from the matching network list below
- 6.Tap Save, then select the new APN to activate it
- 7.Restart the phone or toggle Airplane Mode for 20 seconds
iPhone and iPad
- 1.Open Settings
- 2.Tap Cellular Data or Mobile Data
- 3.Look for Cellular Data Network (only appears on GSM-A and GSM-T lines)
- 4.Enter iPhone values from the matching list below
- 5.For CDMA-V lines, the APN editor is hidden by design. Use Reset Network Settings if connectivity fails

T-Mobile-network Red Pocket (GSM-T):
- Name: Red Pocket T-Mobile
- APN:
wholesale(tryfast.t-mobile.comif the first fails) - MMSC:

- MMS port: 8080
- MCC: 310

- APN Type:

Verizon-network Red Pocket (CDMA-V):
Verizon-network Red Pocket lines auto-configure through a carrier profile. Manual APN entry is typically not available or required. If data fails, use Reset Network Settings to reinstall the carrier profile rather than entering APN values manually.
Red Pocket iPhone APN Values
If your iPhone needs manual entry on a GSM-A or GSM-T line, use the APN value matching your underlying network from the Android lists above. MMS Max Message Size on iPhone is 1048576 (1 MB), and MMS UA Prof URL is http://www.apple.com/mms/uaprof.rdf on all networks.
For CDMA-V (Verizon) Red Pocket lines, the iPhone APN editor is hidden by Verizon's carrier profile. This is normal and prevents accidental misconfiguration. Use Reset Network Settings to refresh the profile when data fails.
Choosing the Right Network APN
The single biggest source of Red Pocket APN trouble is using the wrong APN for the network the SIM is on. The Red Pocket SIM packaging is the most reliable source: GSM-A means AT&T, GSM-T means T-Mobile, CDMA-V means Verizon, CDMA-S means legacy Sprint (now part of T-Mobile).
If you do not have the packaging, the activation email confirms the network. Failing that, check the carrier name in your phone's status bar (it sometimes shows the underlying network briefly during boot) or call Red Pocket support. The underlying network is on file for every active line.
If you bought a phone from one specific carrier (Verizon, AT&T, or T-Mobile) and used a Red Pocket SIM for a different network, the phone may need an unlock. Locked phones often refuse SIMs from third-party MVNOs on other networks.
Red Pocket Connection Fixes
- After saving the Android APN, reboot the phone. Red Pocket sometimes does not switch to the new entry until the device re-registers.
- Confirm the APN value matches your network's SIM label (GSM-A, GSM-T, etc.). Wrong APN means no connection.
- The AT&T APN value
RESELLERis uppercase. Case matters on AT&T's network. - For T-Mobile-network lines, if
wholesalefails, savefast.t-mobile.comas a separate APN and try that instead. - If MMS fails but data works, double-check the MMS port. AT&T uses 80, T-Mobile uses 8080. These are not interchangeable.
- For iPhones, install any pending Carrier Settings update at Settings > General > About.
- If your phone moved from another carrier to Red Pocket, run Reset Network Settings to clear old APN entries before retrying.
Frequently Asked Questions
Why does Red Pocket label SIMs with GSM-A, GSM-T, CDMA-V?
The labels indicate the underlying network. GSM-A is AT&T (GSM-based), GSM-T is T-Mobile (GSM-based), CDMA-V is Verizon (originally CDMA, now LTE). The labels date back to when GSM and CDMA were technically distinct, but Red Pocket kept them as identifiers even after both networks moved to LTE and 5G.
Can I switch my Red Pocket line from AT&T to T-Mobile network?
No. Red Pocket SIMs are network-specific. To switch, contact Red Pocket customer service and request a new SIM provisioned for the target network. Your account and number stay intact.
Why is the Red Pocket AT&T APN in uppercase (RESELLER)?
AT&T's wholesale platform expects the APN value in uppercase as the back-end identifier for reseller traffic. The case sensitivity is enforced by AT&T's network, not Red Pocket. Lowercase or mixed-case will not connect.
Do I need different APN values for 5G on Red Pocket?
No. The same APN handles 4G LTE and 5G on each underlying network. To pull 5G, enable 5G in your phone's network mode settings and confirm your plan includes 5G access.
My Red Pocket Verizon SIM has no APN editor on iPhone. Is that broken?
No. Verizon-network iPhones intentionally hide the APN editor because the carrier provisions the settings through a profile. Red Pocket inherits this behavior. If data fails, use Reset Network Settings, not manual APN entry.
Can I use a Red Pocket SIM in a hotspot or tablet?
Sometimes. The device must support the underlying network's bands and be unlocked. APN configuration is the same as the Android list for the matching network. Some hotspots and tablets do not have an APN editor; in that case, the Red Pocket SIM relies entirely on carrier auto-provisioning.
What does MMS Max Message Size 1048576 mean?
It is the MMS attachment size cap in bytes (exactly 1 MB), the standard across US carriers including Red Pocket on all networks. Larger files should go through iMessage, RCS, or Wi-Fi-based messaging instead.
