What is Network mode GSM WCDMA?
In a nutshell: GSM = 2G, WCDMA = 3G. GSM uses less power and has limited data speed (~144kbps) WCDMA uses more power and has good data speed (~2+Mbps) For auto-switching between 2G/3G modes, use the “GSM/WCDMA auto” mode (system balances speed vs battery use based on current signal strength).
What does WCDMA network mean?
Wideband Code Division Multiple Access
WCDMA (Wideband Code Division Multiple Access) UMTS standard for 3G digital mobile networks, using CDMA technology. It is the evolution path for GSM and EDGE to UMTS and offers increased voice capacity and theoretical peak data speeds of up to 2 Mbps.

Which is better GSM or Wcdma?
The efficiency and speed are better in WCDMA due to the technology used in the network and the coding channel separating the data columns in the system. This helps to manage the communication channel well in the network and the communication is done faster than GSM. The efficiency and speed are less in GSM.
Which is better GSM or WCDMA?
Which is faster WCDMA or LTE?
When the data rates are compared, LTE provides massive downlink and uplink speeds than WCDMA. In general, WCDMA is considered as 3G technology while LTE is considered as 4G technology. LTE provides higher data rates than WCDMA by achieving higher spectral efficiency.
How do I convert GSM to LTE?
- Navigate to Settings and select More Networks.
- Tap Mobile Networks.
- Tap Network Mode.
- Tap LTE/WCDMA/GSM.
How do you tell if my phone is GSM or CDMA?
For Android users: Go to Settings ➤ System ➤ About Phone. Click on Status to look for an MEID, ESN, or IMEI number. If the device has MEID or ESN numbers, it’s a CDMA phone.
When to use GSM only or WCDMA mode?
GSM only – 2G only mode. When 2G signal strength is low, you get no data. WCDMA only – 3G only mode. When 3G signal strength is low, you get no data.
How to auto switch between GSM and CDMA?
GSM/CDMA auto (PRL) – auto-switching between GSM and CDMA capabilities. In a nutshell: GSM = 2G, WCDMA = 3G. For auto-switching between 2G/3G modes, use the “GSM/WCDMA auto” mode (system balances speed vs battery use based on current signal strength). For 2G-only battery saving mode, use “GSM only”.
Which is the network mode on Android 4.x?
Under Android 4.x variants, if you check under Mobile Network settings, you may notice “Network Mode” with the following possible options (not all may be visible in all devices): GSM/WCDMA (auto connect) – automatically switches between 2G/3G modes. GSM only – 2G only mode. When 2G signal strength is low, you get no data. WCDMA only – 3G only mode.
Can a GSM phone connect to a 3G network?
If you select LTE/GSM/WCDMA (Auto mode), your mobile phone automatically switches between the two network modes provided you’re within range of a 3G or 4G network. If you select GSM only, you can’t achieve high data speeds. If you select WCDMA only, your mobile phone can only connect to 3G networks. Tap the Home key to return to the home screen.
